Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31662, here are decompositions:
- 5 + 31657 = 31662
- 13 + 31649 = 31662
- 19 + 31643 = 31662
- 61 + 31601 = 31662
- 79 + 31583 = 31662
- 89 + 31573 = 31662
- 131 + 31531 = 31662
- 149 + 31513 = 31662
Showing the first eight; more decompositions exist.
