Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731564, here are decompositions:
- 53 + 8731511 = 8731564
- 71 + 8731493 = 8731564
- 131 + 8731433 = 8731564
- 137 + 8731427 = 8731564
- 251 + 8731313 = 8731564
- 263 + 8731301 = 8731564
- 353 + 8731211 = 8731564
- 461 + 8731103 = 8731564
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,731,564 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8731564 first appears in π at position 669,063 of the decimal expansion (the 669,063ordinal-suffix:rd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
