Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538332, here are decompositions:
- 3 + 31538329 = 31538332
- 5 + 31538327 = 31538332
- 71 + 31538261 = 31538332
- 179 + 31538153 = 31538332
- 191 + 31538141 = 31538332
- 269 + 31538063 = 31538332
- 443 + 31537889 = 31538332
- 461 + 31537871 = 31538332
Showing the first eight; more decompositions exist.
