Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1182, here are decompositions:
- 11 + 1171 = 1182
- 19 + 1163 = 1182
- 29 + 1153 = 1182
- 31 + 1151 = 1182
- 53 + 1129 = 1182
- 59 + 1123 = 1182
- 73 + 1109 = 1182
- 79 + 1103 = 1182
Showing the first eight; more decompositions exist.
