Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19118, here are decompositions:
- 31 + 19087 = 19118
- 37 + 19081 = 19118
- 67 + 19051 = 19118
- 109 + 19009 = 19118
- 139 + 18979 = 19118
- 199 + 18919 = 19118
- 331 + 18787 = 19118
- 439 + 18679 = 19118
Showing the first eight; more decompositions exist.
