Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12090, here are decompositions:
- 17 + 12073 = 12090
- 19 + 12071 = 12090
- 41 + 12049 = 12090
- 47 + 12043 = 12090
- 53 + 12037 = 12090
- 79 + 12011 = 12090
- 83 + 12007 = 12090
- 103 + 11987 = 12090
Showing the first eight; more decompositions exist.
