Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101398, here are decompositions:
- 131 + 101267 = 101398
- 191 + 101207 = 101398
- 239 + 101159 = 101398
- 257 + 101141 = 101398
- 281 + 101117 = 101398
- 317 + 101081 = 101398
- 347 + 101051 = 101398
- 389 + 101009 = 101398
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 101,398 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 101398 first appears in π at position 322,533 of the decimal expansion (the 322,533ordinal-suffix:rd 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.
