Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19078, here are decompositions:
- 5 + 19073 = 19078
- 41 + 19037 = 19078
- 47 + 19031 = 19078
- 131 + 18947 = 19078
- 167 + 18911 = 19078
- 179 + 18899 = 19078
- 239 + 18839 = 19078
- 281 + 18797 = 19078
Showing the first eight; more decompositions exist.
