Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537446, here are decompositions:
- 13 + 31537433 = 31537446
- 37 + 31537409 = 31537446
- 107 + 31537339 = 31537446
- 137 + 31537309 = 31537446
- 139 + 31537307 = 31537446
- 173 + 31537273 = 31537446
- 179 + 31537267 = 31537446
- 223 + 31537223 = 31537446
Showing the first eight; more decompositions exist.
