Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632440, here are decompositions:

17 + 8632423 = 8632440
29 + 8632411 = 8632440
41 + 8632399 = 8632440
53 + 8632387 = 8632440
59 + 8632381 = 8632440
73 + 8632367 = 8632440
79 + 8632361 = 8632440
83 + 8632357 = 8632440

Showing the first eight; more decompositions exist.
