Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148748, here are decompositions:
- 37 + 148711 = 148748
- 79 + 148669 = 148748
- 109 + 148639 = 148748
- 139 + 148609 = 148748
- 199 + 148549 = 148748
- 211 + 148537 = 148748
- 277 + 148471 = 148748
- 337 + 148411 = 148748
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 148,748 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 148748 first appears in π at position 985,869 of the decimal expansion (the 985,869ordinal-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.
