Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733780, here are decompositions:

37 + 8733743 = 8733780
43 + 8733737 = 8733780
61 + 8733719 = 8733780
67 + 8733713 = 8733780
71 + 8733709 = 8733780
73 + 8733707 = 8733780
79 + 8733701 = 8733780
89 + 8733691 = 8733780

Showing the first eight; more decompositions exist.
