Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742572, here are decompositions:

31 + 8742541 = 8742572
43 + 8742529 = 8742572
61 + 8742511 = 8742572
73 + 8742499 = 8742572
79 + 8742493 = 8742572
103 + 8742469 = 8742572
109 + 8742463 = 8742572
151 + 8742421 = 8742572

Showing the first eight; more decompositions exist.
