Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560672, here are decompositions:
- 41 + 31560631 = 31560672
- 43 + 31560629 = 31560672
- 83 + 31560589 = 31560672
- 89 + 31560583 = 31560672
- 103 + 31560569 = 31560672
- 113 + 31560559 = 31560672
- 131 + 31560541 = 31560672
- 139 + 31560533 = 31560672
Showing the first eight; more decompositions exist.
