Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31056, here are decompositions:
- 5 + 31051 = 31056
- 17 + 31039 = 31056
- 23 + 31033 = 31056
- 37 + 31019 = 31056
- 43 + 31013 = 31056
- 73 + 30983 = 31056
- 79 + 30977 = 31056
- 107 + 30949 = 31056
Showing the first eight; more decompositions exist.
