Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31136, here are decompositions:
- 13 + 31123 = 31136
- 67 + 31069 = 31136
- 73 + 31063 = 31136
- 97 + 31039 = 31136
- 103 + 31033 = 31136
- 199 + 30937 = 31136
- 277 + 30859 = 31136
- 283 + 30853 = 31136
Showing the first eight; more decompositions exist.
