Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1130, here are decompositions:
- 7 + 1123 = 1130
- 13 + 1117 = 1130
- 37 + 1093 = 1130
- 43 + 1087 = 1130
- 61 + 1069 = 1130
- 67 + 1063 = 1130
- 79 + 1051 = 1130
- 97 + 1033 = 1130
Showing the first eight; more decompositions exist.
