Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637774, here are decompositions:

73 + 8637701 = 8637774
107 + 8637667 = 8637774
137 + 8637637 = 8637774
157 + 8637617 = 8637774
163 + 8637611 = 8637774
251 + 8637523 = 8637774
281 + 8637493 = 8637774
283 + 8637491 = 8637774

Showing the first eight; more decompositions exist.
