Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051222, here are decompositions:

41 + 1051181 = 1051222
71 + 1051151 = 1051222
83 + 1051139 = 1051222
449 + 1050773 = 1051222
479 + 1050743 = 1051222
509 + 1050713 = 1051222
659 + 1050563 = 1051222
719 + 1050503 = 1051222

Showing the first eight; more decompositions exist.
