Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31232, here are decompositions:
- 13 + 31219 = 31232
- 43 + 31189 = 31232
- 73 + 31159 = 31232
- 79 + 31153 = 31232
- 109 + 31123 = 31232
- 151 + 31081 = 31232
- 163 + 31069 = 31232
- 181 + 31051 = 31232
Showing the first eight; more decompositions exist.
