Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638758, here are decompositions:

31 + 8638727 = 8638758
61 + 8638697 = 8638758
67 + 8638691 = 8638758
71 + 8638687 = 8638758
97 + 8638661 = 8638758
131 + 8638627 = 8638758
137 + 8638621 = 8638758
241 + 8638517 = 8638758

Showing the first eight; more decompositions exist.
