Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055218, here are decompositions:

29 + 1055189 = 1055218
179 + 1055039 = 1055218
449 + 1054769 = 1055218
569 + 1054649 = 1055218
641 + 1054577 = 1055218
701 + 1054517 = 1055218
761 + 1054457 = 1055218
881 + 1054337 = 1055218

Showing the first eight; more decompositions exist.
