Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527994, here are decompositions:
- 53 + 31527941 = 31527994
- 107 + 31527887 = 31527994
- 167 + 31527827 = 31527994
- 293 + 31527701 = 31527994
- 317 + 31527677 = 31527994
- 461 + 31527533 = 31527994
- 503 + 31527491 = 31527994
- 587 + 31527407 = 31527994
Showing the first eight; more decompositions exist.
