Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742608, here are decompositions:

31 + 8742577 = 8742608
37 + 8742571 = 8742608
67 + 8742541 = 8742608
79 + 8742529 = 8742608
97 + 8742511 = 8742608
109 + 8742499 = 8742608
139 + 8742469 = 8742608
229 + 8742379 = 8742608

Showing the first eight; more decompositions exist.
