Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040278, here are decompositions:

59 + 1040219 = 1040278
89 + 1040189 = 1040278
137 + 1040141 = 1040278
227 + 1040051 = 1040278
257 + 1040021 = 1040278
347 + 1039931 = 1040278
461 + 1039817 = 1040278
479 + 1039799 = 1040278

Showing the first eight; more decompositions exist.
