Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609584, here are decompositions:
- 7 + 31609577 = 31609584
- 23 + 31609561 = 31609584
- 37 + 31609547 = 31609584
- 43 + 31609541 = 31609584
- 53 + 31609531 = 31609584
- 103 + 31609481 = 31609584
- 131 + 31609453 = 31609584
- 191 + 31609393 = 31609584
Showing the first eight; more decompositions exist.
