Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19170, here are decompositions:
- 7 + 19163 = 19170
- 13 + 19157 = 19170
- 29 + 19141 = 19170
- 31 + 19139 = 19170
- 83 + 19087 = 19170
- 89 + 19081 = 19170
- 97 + 19073 = 19170
- 101 + 19069 = 19170
Showing the first eight; more decompositions exist.
