Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609232, here are decompositions:
- 3 + 31609229 = 31609232
- 19 + 31609213 = 31609232
- 43 + 31609189 = 31609232
- 139 + 31609093 = 31609232
- 199 + 31609033 = 31609232
- 349 + 31608883 = 31609232
- 379 + 31608853 = 31609232
- 409 + 31608823 = 31609232
Showing the first eight; more decompositions exist.
