Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145702, here are decompositions:
- 23 + 145679 = 145702
- 41 + 145661 = 145702
- 59 + 145643 = 145702
- 101 + 145601 = 145702
- 113 + 145589 = 145702
- 191 + 145511 = 145702
- 239 + 145463 = 145702
- 251 + 145451 = 145702
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 145,702 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 145702 first appears in π at position 261,142 of the decimal expansion (the 261,142ordinal-suffix:nd 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.
