Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743806, here are decompositions:

37 + 8743769 = 8743806
53 + 8743753 = 8743806
59 + 8743747 = 8743806
73 + 8743733 = 8743806
89 + 8743717 = 8743806
167 + 8743639 = 8743806
173 + 8743633 = 8743806
223 + 8743583 = 8743806

Showing the first eight; more decompositions exist.
