Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150808, here are decompositions:
- 11 + 150797 = 150808
- 17 + 150791 = 150808
- 29 + 150779 = 150808
- 41 + 150767 = 150808
- 101 + 150707 = 150808
- 149 + 150659 = 150808
- 191 + 150617 = 150808
- 197 + 150611 = 150808
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 150,808 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 150808 first appears in π at position 168,137 of the decimal expansion (the 168,137ordinal-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.
