Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611190, here are decompositions:
- 3 + 31611187 = 31611190
- 53 + 31611137 = 31611190
- 89 + 31611101 = 31611190
- 101 + 31611089 = 31611190
- 167 + 31611023 = 31611190
- 173 + 31611017 = 31611190
- 179 + 31611011 = 31611190
- 419 + 31610771 = 31611190
Showing the first eight; more decompositions exist.
