Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015426, here are decompositions:

3 + 1015423 = 1015426
17 + 1015409 = 1015426
23 + 1015403 = 1015426
59 + 1015367 = 1015426
149 + 1015277 = 1015426
227 + 1015199 = 1015426
263 + 1015163 = 1015426
353 + 1015073 = 1015426

Showing the first eight; more decompositions exist.
