Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594500, here are decompositions:
- 11 + 31594489 = 31594500
- 37 + 31594463 = 31594500
- 71 + 31594429 = 31594500
- 79 + 31594421 = 31594500
- 101 + 31594399 = 31594500
- 107 + 31594393 = 31594500
- 127 + 31594373 = 31594500
- 149 + 31594351 = 31594500
Showing the first eight; more decompositions exist.
