Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527236, here are decompositions:
- 3 + 31527233 = 31527236
- 43 + 31527193 = 31527236
- 79 + 31527157 = 31527236
- 127 + 31527109 = 31527236
- 283 + 31526953 = 31527236
- 337 + 31526899 = 31527236
- 373 + 31526863 = 31527236
- 463 + 31526773 = 31527236
Showing the first eight; more decompositions exist.
