Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1104, here are decompositions:
- 7 + 1097 = 1104
- 11 + 1093 = 1104
- 13 + 1091 = 1104
- 17 + 1087 = 1104
- 41 + 1063 = 1104
- 43 + 1061 = 1104
- 53 + 1051 = 1104
- 71 + 1033 = 1104
Showing the first eight; more decompositions exist.
