Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742612, here are decompositions:

41 + 8742571 = 8742612
61 + 8742551 = 8742612
71 + 8742541 = 8742612
83 + 8742529 = 8742612
101 + 8742511 = 8742612
113 + 8742499 = 8742612
149 + 8742463 = 8742612
163 + 8742449 = 8742612

Showing the first eight; more decompositions exist.
