Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742630, here are decompositions:

7 + 8742623 = 8742630
53 + 8742577 = 8742630
59 + 8742571 = 8742630
79 + 8742551 = 8742630
89 + 8742541 = 8742630
101 + 8742529 = 8742630
131 + 8742499 = 8742630
137 + 8742493 = 8742630

Showing the first eight; more decompositions exist.
