Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540314, here are decompositions:
- 5 + 31540309 = 31540314
- 17 + 31540297 = 31540314
- 53 + 31540261 = 31540314
- 73 + 31540241 = 31540314
- 97 + 31540217 = 31540314
- 101 + 31540213 = 31540314
- 103 + 31540211 = 31540314
- 107 + 31540207 = 31540314
Showing the first eight; more decompositions exist.
