Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31802, here are decompositions:
- 3 + 31799 = 31802
- 31 + 31771 = 31802
- 61 + 31741 = 31802
- 73 + 31729 = 31802
- 79 + 31723 = 31802
- 103 + 31699 = 31802
- 139 + 31663 = 31802
- 229 + 31573 = 31802
Showing the first eight; more decompositions exist.
