Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145648, here are decompositions:
- 5 + 145643 = 145648
- 11 + 145637 = 145648
- 47 + 145601 = 145648
- 59 + 145589 = 145648
- 71 + 145577 = 145648
- 101 + 145547 = 145648
- 131 + 145517 = 145648
- 137 + 145511 = 145648
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 145,648 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 145648 first appears in π at position 250 of the decimal expansion (the 250ordinal-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.
