Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18122, here are decompositions:
- 3 + 18119 = 18122
- 61 + 18061 = 18122
- 73 + 18049 = 18122
- 79 + 18043 = 18122
- 109 + 18013 = 18122
- 151 + 17971 = 18122
- 163 + 17959 = 18122
- 193 + 17929 = 18122
Showing the first eight; more decompositions exist.
