Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538374, here are decompositions:
- 3 + 31538371 = 31538374
- 41 + 31538333 = 31538374
- 47 + 31538327 = 31538374
- 113 + 31538261 = 31538374
- 167 + 31538207 = 31538374
- 233 + 31538141 = 31538374
- 311 + 31538063 = 31538374
- 503 + 31537871 = 31538374
Showing the first eight; more decompositions exist.
