Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649412, here are decompositions:

3 + 8649409 = 8649412
29 + 8649383 = 8649412
41 + 8649371 = 8649412
59 + 8649353 = 8649412
89 + 8649323 = 8649412
113 + 8649299 = 8649412
173 + 8649239 = 8649412
383 + 8649029 = 8649412

Showing the first eight; more decompositions exist.
