Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538104, here are decompositions:
- 41 + 31538063 = 31538104
- 71 + 31538033 = 31538104
- 107 + 31537997 = 31538104
- 233 + 31537871 = 31538104
- 281 + 31537823 = 31538104
- 383 + 31537721 = 31538104
- 557 + 31537547 = 31538104
- 797 + 31537307 = 31538104
Showing the first eight; more decompositions exist.
