Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138598, here are decompositions:
- 11 + 138587 = 138598
- 17 + 138581 = 138598
- 29 + 138569 = 138598
- 101 + 138497 = 138598
- 137 + 138461 = 138598
- 149 + 138449 = 138598
- 191 + 138407 = 138598
- 197 + 138401 = 138598
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 138,598 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 138598 first appears in π at position 117,324 of the decimal expansion (the 117,324ordinal-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.
