Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534800, here are decompositions:
- 13 + 31534787 = 31534800
- 43 + 31534757 = 31534800
- 47 + 31534753 = 31534800
- 61 + 31534739 = 31534800
- 71 + 31534729 = 31534800
- 109 + 31534691 = 31534800
- 131 + 31534669 = 31534800
- 149 + 31534651 = 31534800
Showing the first eight; more decompositions exist.
