Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527996, here are decompositions:
- 29 + 31527967 = 31527996
- 83 + 31527913 = 31527996
- 109 + 31527887 = 31527996
- 167 + 31527829 = 31527996
- 179 + 31527817 = 31527996
- 293 + 31527703 = 31527996
- 307 + 31527689 = 31527996
- 337 + 31527659 = 31527996
Showing the first eight; more decompositions exist.
