Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1046440, here are decompositions:

41 + 1046399 = 1046440
47 + 1046393 = 1046440
71 + 1046369 = 1046440
89 + 1046351 = 1046440
233 + 1046207 = 1046440
251 + 1046189 = 1046440
257 + 1046183 = 1046440
359 + 1046081 = 1046440

Showing the first eight; more decompositions exist.
