Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538464, here are decompositions:
- 53 + 31538411 = 31538464
- 131 + 31538333 = 31538464
- 137 + 31538327 = 31538464
- 257 + 31538207 = 31538464
- 311 + 31538153 = 31538464
- 401 + 31538063 = 31538464
- 431 + 31538033 = 31538464
- 467 + 31537997 = 31538464
Showing the first eight; more decompositions exist.
