Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1102, here are decompositions:
- 5 + 1097 = 1102
- 11 + 1091 = 1102
- 41 + 1061 = 1102
- 53 + 1049 = 1102
- 71 + 1031 = 1102
- 83 + 1019 = 1102
- 89 + 1013 = 1102
- 131 + 971 = 1102
Showing the first eight; more decompositions exist.
