Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31020, here are decompositions:
- 7 + 31013 = 31020
- 37 + 30983 = 31020
- 43 + 30977 = 31020
- 71 + 30949 = 31020
- 79 + 30941 = 31020
- 83 + 30937 = 31020
- 89 + 30931 = 31020
- 109 + 30911 = 31020
Showing the first eight; more decompositions exist.
