Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526984, here are decompositions:
- 31 + 31526953 = 31526984
- 43 + 31526941 = 31526984
- 103 + 31526881 = 31526984
- 193 + 31526791 = 31526984
- 211 + 31526773 = 31526984
- 271 + 31526713 = 31526984
- 337 + 31526647 = 31526984
- 367 + 31526617 = 31526984
Showing the first eight; more decompositions exist.
