Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538794, here are decompositions:
- 5 + 31538789 = 31538794
- 41 + 31538753 = 31538794
- 83 + 31538711 = 31538794
- 101 + 31538693 = 31538794
- 233 + 31538561 = 31538794
- 317 + 31538477 = 31538794
- 383 + 31538411 = 31538794
- 461 + 31538333 = 31538794
Showing the first eight; more decompositions exist.
