Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742530, here are decompositions:

19 + 8742511 = 8742530
31 + 8742499 = 8742530
37 + 8742493 = 8742530
61 + 8742469 = 8742530
67 + 8742463 = 8742530
109 + 8742421 = 8742530
151 + 8742379 = 8742530
163 + 8742367 = 8742530

Showing the first eight; more decompositions exist.
