Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586, here are decompositions:
- 3 + 31583 = 31586
- 13 + 31573 = 31586
- 19 + 31567 = 31586
- 43 + 31543 = 31586
- 73 + 31513 = 31586
- 97 + 31489 = 31586
- 109 + 31477 = 31586
- 193 + 31393 = 31586
Showing the first eight; more decompositions exist.
