Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738518, here are decompositions:

11 + 8738507 = 8738518
71 + 8738447 = 8738518
167 + 8738351 = 8738518
179 + 8738339 = 8738518
317 + 8738201 = 8738518
389 + 8738129 = 8738518
431 + 8738087 = 8738518
647 + 8737871 = 8738518

Showing the first eight; more decompositions exist.
