Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31722, here are decompositions:
- 23 + 31699 = 31722
- 59 + 31663 = 31722
- 73 + 31649 = 31722
- 79 + 31643 = 31722
- 139 + 31583 = 31722
- 149 + 31573 = 31722
- 179 + 31543 = 31722
- 181 + 31541 = 31722
Showing the first eight; more decompositions exist.
