Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143564, here are decompositions:
- 13 + 143551 = 143564
- 37 + 143527 = 143564
- 61 + 143503 = 143564
- 97 + 143467 = 143564
- 103 + 143461 = 143564
- 151 + 143413 = 143564
- 163 + 143401 = 143564
- 277 + 143287 = 143564
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 143,564 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 143564 first appears in π at position 991,057 of the decimal expansion (the 991,057ordinal-suffix:th 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.
