Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041778, here are decompositions:

41 + 1041737 = 1041778
47 + 1041731 = 1041778
107 + 1041671 = 1041778
281 + 1041497 = 1041778
317 + 1041461 = 1041778
449 + 1041329 = 1041778
461 + 1041317 = 1041778
467 + 1041311 = 1041778

Showing the first eight; more decompositions exist.
