Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743222, here are decompositions:

53 + 8743169 = 8743222
83 + 8743139 = 8743222
101 + 8743121 = 8743222
179 + 8743043 = 8743222
281 + 8742941 = 8743222
401 + 8742821 = 8743222
443 + 8742779 = 8743222
569 + 8742653 = 8743222

Showing the first eight; more decompositions exist.
