Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31162, here are decompositions:
- 3 + 31159 = 31162
- 11 + 31151 = 31162
- 23 + 31139 = 31162
- 41 + 31121 = 31162
- 71 + 31091 = 31162
- 83 + 31079 = 31162
- 149 + 31013 = 31162
- 179 + 30983 = 31162
Showing the first eight; more decompositions exist.
