Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538074, here are decompositions:
- 3 + 31538071 = 31538074
- 11 + 31538063 = 31538074
- 41 + 31538033 = 31538074
- 251 + 31537823 = 31538074
- 353 + 31537721 = 31538074
- 383 + 31537691 = 31538074
- 443 + 31537631 = 31538074
- 593 + 31537481 = 31538074
Showing the first eight; more decompositions exist.
