Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049278, here are decompositions:

59 + 1049219 = 1049278
101 + 1049177 = 1049278
107 + 1049171 = 1049278
137 + 1049141 = 1049278
149 + 1049129 = 1049278
227 + 1049051 = 1049278
239 + 1049039 = 1049278
359 + 1048919 = 1049278

Showing the first eight; more decompositions exist.
