Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742690, here are decompositions:

13 + 8742677 = 8742690
17 + 8742673 = 8742690
37 + 8742653 = 8742690
53 + 8742637 = 8742690
67 + 8742623 = 8742690
113 + 8742577 = 8742690
139 + 8742551 = 8742690
149 + 8742541 = 8742690

Showing the first eight; more decompositions exist.
