Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538796, here are decompositions:
- 7 + 31538789 = 31538796
- 17 + 31538779 = 31538796
- 43 + 31538753 = 31538796
- 53 + 31538743 = 31538796
- 67 + 31538729 = 31538796
- 83 + 31538713 = 31538796
- 103 + 31538693 = 31538796
- 167 + 31538629 = 31538796
Showing the first eight; more decompositions exist.
