Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457752, here are decompositions:
- 23 + 31457729 = 31457752
- 71 + 31457681 = 31457752
- 149 + 31457603 = 31457752
- 239 + 31457513 = 31457752
- 281 + 31457471 = 31457752
- 449 + 31457303 = 31457752
- 593 + 31457159 = 31457752
- 653 + 31457099 = 31457752
Showing the first eight; more decompositions exist.
