Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607506, here are decompositions:
- 3 + 31607503 = 31607506
- 17 + 31607489 = 31607506
- 59 + 31607447 = 31607506
- 83 + 31607423 = 31607506
- 107 + 31607399 = 31607506
- 149 + 31607357 = 31607506
- 179 + 31607327 = 31607506
- 197 + 31607309 = 31607506
Showing the first eight; more decompositions exist.
