Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540104, here are decompositions:
- 5 + 31540099 = 31540104
- 41 + 31540063 = 31540104
- 73 + 31540031 = 31540104
- 97 + 31540007 = 31540104
- 137 + 31539967 = 31540104
- 173 + 31539931 = 31540104
- 241 + 31539863 = 31540104
- 283 + 31539821 = 31540104
Showing the first eight; more decompositions exist.
