Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461250, here are decompositions:
- 59 + 31461191 = 31461250
- 71 + 31461179 = 31461250
- 89 + 31461161 = 31461250
- 101 + 31461149 = 31461250
- 137 + 31461113 = 31461250
- 239 + 31461011 = 31461250
- 419 + 31460831 = 31461250
- 467 + 31460783 = 31461250
Showing the first eight; more decompositions exist.
