Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91400, here are decompositions:
- 3 + 91397 = 91400
- 7 + 91393 = 91400
- 13 + 91387 = 91400
- 19 + 91381 = 91400
- 31 + 91369 = 91400
- 97 + 91303 = 91400
- 103 + 91297 = 91400
- 109 + 91291 = 91400
Showing the first eight; more decompositions exist.
