Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31160, here are decompositions:
- 7 + 31153 = 31160
- 13 + 31147 = 31160
- 37 + 31123 = 31160
- 79 + 31081 = 31160
- 97 + 31063 = 31160
- 109 + 31051 = 31160
- 127 + 31033 = 31160
- 211 + 30949 = 31160
Showing the first eight; more decompositions exist.
