Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611318, here are decompositions:
- 7 + 31611311 = 31611318
- 17 + 31611301 = 31611318
- 19 + 31611299 = 31611318
- 47 + 31611271 = 31611318
- 131 + 31611187 = 31611318
- 181 + 31611137 = 31611318
- 191 + 31611127 = 31611318
- 229 + 31611089 = 31611318
Showing the first eight; more decompositions exist.
