Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18230, here are decompositions:
- 7 + 18223 = 18230
- 13 + 18217 = 18230
- 19 + 18211 = 18230
- 31 + 18199 = 18230
- 61 + 18169 = 18230
- 97 + 18133 = 18230
- 103 + 18127 = 18230
- 109 + 18121 = 18230
Showing the first eight; more decompositions exist.
