Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91398, here are decompositions:
- 5 + 91393 = 91398
- 11 + 91387 = 91398
- 17 + 91381 = 91398
- 29 + 91369 = 91398
- 31 + 91367 = 91398
- 67 + 91331 = 91398
- 89 + 91309 = 91398
- 101 + 91297 = 91398
Showing the first eight; more decompositions exist.
