Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131392, here are decompositions:
- 11 + 131381 = 131392
- 29 + 131363 = 131392
- 71 + 131321 = 131392
- 89 + 131303 = 131392
- 179 + 131213 = 131392
- 263 + 131129 = 131392
- 281 + 131111 = 131392
- 383 + 131009 = 131392
Showing the first eight; more decompositions exist.
