Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622400, here are decompositions:
- 11 + 31622389 = 31622400
- 23 + 31622377 = 31622400
- 31 + 31622369 = 31622400
- 53 + 31622347 = 31622400
- 107 + 31622293 = 31622400
- 113 + 31622287 = 31622400
- 127 + 31622273 = 31622400
- 163 + 31622237 = 31622400
Showing the first eight; more decompositions exist.
