Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496388, here are decompositions:
- 17 + 31496371 = 31496388
- 19 + 31496369 = 31496388
- 59 + 31496329 = 31496388
- 67 + 31496321 = 31496388
- 71 + 31496317 = 31496388
- 127 + 31496261 = 31496388
- 167 + 31496221 = 31496388
- 179 + 31496209 = 31496388
Showing the first eight; more decompositions exist.
