Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528028, here are decompositions:
- 31 + 31527997 = 31528028
- 61 + 31527967 = 31528028
- 97 + 31527931 = 31528028
- 199 + 31527829 = 31528028
- 211 + 31527817 = 31528028
- 241 + 31527787 = 31528028
- 331 + 31527697 = 31528028
- 487 + 31527541 = 31528028
Showing the first eight; more decompositions exist.
