Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538696, here are decompositions:
- 3 + 31538693 = 31538696
- 43 + 31538653 = 31538696
- 67 + 31538629 = 31538696
- 73 + 31538623 = 31538696
- 127 + 31538569 = 31538696
- 139 + 31538557 = 31538696
- 157 + 31538539 = 31538696
- 193 + 31538503 = 31538696
Showing the first eight; more decompositions exist.
