Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649742, here are decompositions:

53 + 8649689 = 8649742
71 + 8649671 = 8649742
113 + 8649629 = 8649742
131 + 8649611 = 8649742
251 + 8649491 = 8649742
263 + 8649479 = 8649742
359 + 8649383 = 8649742
389 + 8649353 = 8649742

Showing the first eight; more decompositions exist.
