Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609456, here are decompositions:
- 3 + 31609453 = 31609456
- 5 + 31609451 = 31609456
- 167 + 31609289 = 31609456
- 227 + 31609229 = 31609456
- 233 + 31609223 = 31609456
- 503 + 31608953 = 31609456
- 563 + 31608893 = 31609456
- 569 + 31608887 = 31609456
Showing the first eight; more decompositions exist.
