Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588422, here are decompositions:
- 23 + 31588399 = 31588422
- 53 + 31588369 = 31588422
- 71 + 31588351 = 31588422
- 101 + 31588321 = 31588422
- 109 + 31588313 = 31588422
- 223 + 31588199 = 31588422
- 251 + 31588171 = 31588422
- 293 + 31588129 = 31588422
Showing the first eight; more decompositions exist.
