Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734638, here are decompositions:

61 + 8734577 = 8734638
67 + 8734571 = 8734638
127 + 8734511 = 8734638
131 + 8734507 = 8734638
137 + 8734501 = 8734638
197 + 8734441 = 8734638
251 + 8734387 = 8734638
271 + 8734367 = 8734638

Showing the first eight; more decompositions exist.
