Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540116, here are decompositions:
- 7 + 31540109 = 31540116
- 17 + 31540099 = 31540116
- 53 + 31540063 = 31540116
- 103 + 31540013 = 31540116
- 107 + 31540009 = 31540116
- 109 + 31540007 = 31540116
- 149 + 31539967 = 31540116
- 227 + 31539889 = 31540116
Showing the first eight; more decompositions exist.
