Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742152, here are decompositions:
- 19 + 8742133 = 8742152
- 31 + 8742121 = 8742152
- 163 + 8741989 = 8742152
- 229 + 8741923 = 8742152
- 241 + 8741911 = 8742152
- 313 + 8741839 = 8742152
- 373 + 8741779 = 8742152
- 409 + 8741743 = 8742152
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 8,742,152 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 8742152 first appears in π at position 791,554 of the decimal expansion (the 791,554ordinal-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.
