Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19182, here are decompositions:
- 19 + 19163 = 19182
- 41 + 19141 = 19182
- 43 + 19139 = 19182
- 61 + 19121 = 19182
- 101 + 19081 = 19182
- 103 + 19079 = 19182
- 109 + 19073 = 19182
- 113 + 19069 = 19182
Showing the first eight; more decompositions exist.
