Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528002, here are decompositions:
- 5 + 31527997 = 31528002
- 61 + 31527941 = 31528002
- 71 + 31527931 = 31528002
- 89 + 31527913 = 31528002
- 173 + 31527829 = 31528002
- 293 + 31527709 = 31528002
- 313 + 31527689 = 31528002
- 419 + 31527583 = 31528002
Showing the first eight; more decompositions exist.
