Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609750, here are decompositions:
- 47 + 31609703 = 31609750
- 59 + 31609691 = 31609750
- 71 + 31609679 = 31609750
- 89 + 31609661 = 31609750
- 167 + 31609583 = 31609750
- 173 + 31609577 = 31609750
- 251 + 31609499 = 31609750
- 257 + 31609493 = 31609750
Showing the first eight; more decompositions exist.
