Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19126, here are decompositions:
- 5 + 19121 = 19126
- 47 + 19079 = 19126
- 53 + 19073 = 19126
- 89 + 19037 = 19126
- 113 + 19013 = 19126
- 167 + 18959 = 19126
- 179 + 18947 = 19126
- 227 + 18899 = 19126
Showing the first eight; more decompositions exist.
