Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1086, here are decompositions:
- 17 + 1069 = 1086
- 23 + 1063 = 1086
- 37 + 1049 = 1086
- 47 + 1039 = 1086
- 53 + 1033 = 1086
- 67 + 1019 = 1086
- 73 + 1013 = 1086
- 89 + 997 = 1086
Showing the first eight; more decompositions exist.
