Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18272, here are decompositions:
- 3 + 18269 = 18272
- 19 + 18253 = 18272
- 43 + 18229 = 18272
- 61 + 18211 = 18272
- 73 + 18199 = 18272
- 103 + 18169 = 18272
- 139 + 18133 = 18272
- 151 + 18121 = 18272
Showing the first eight; more decompositions exist.
