Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145626, here are decompositions:
- 23 + 145603 = 145626
- 37 + 145589 = 145626
- 79 + 145547 = 145626
- 83 + 145543 = 145626
- 109 + 145517 = 145626
- 113 + 145513 = 145626
- 139 + 145487 = 145626
- 149 + 145477 = 145626
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 145,626 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 145626 first appears in π at position 437,910 of the decimal expansion (the 437,910ordinal-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.
