Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145602, here are decompositions:
- 13 + 145589 = 145602
- 53 + 145549 = 145602
- 59 + 145543 = 145602
- 71 + 145531 = 145602
- 89 + 145513 = 145602
- 101 + 145501 = 145602
- 131 + 145471 = 145602
- 139 + 145463 = 145602
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 145,602 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 145602 first appears in π at position 400,544 of the decimal expansion (the 400,544ordinal-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.
