Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531004, here are decompositions:
- 3 + 31531001 = 31531004
- 31 + 31530973 = 31531004
- 61 + 31530943 = 31531004
- 103 + 31530901 = 31531004
- 163 + 31530841 = 31531004
- 367 + 31530637 = 31531004
- 397 + 31530607 = 31531004
- 433 + 31530571 = 31531004
Showing the first eight; more decompositions exist.
