Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148248, here are decompositions:
- 5 + 148243 = 148248
- 19 + 148229 = 148248
- 41 + 148207 = 148248
- 47 + 148201 = 148248
- 97 + 148151 = 148248
- 101 + 148147 = 148248
- 109 + 148139 = 148248
- 157 + 148091 = 148248
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 148,248 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 148248 first appears in π at position 346,511 of the decimal expansion (the 346,511ordinal-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.
