Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742684, here are decompositions:

7 + 8742677 = 8742684
11 + 8742673 = 8742684
31 + 8742653 = 8742684
47 + 8742637 = 8742684
61 + 8742623 = 8742684
107 + 8742577 = 8742684
113 + 8742571 = 8742684
173 + 8742511 = 8742684

Showing the first eight; more decompositions exist.
