Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742672, here are decompositions:

19 + 8742653 = 8742672
101 + 8742571 = 8742672
131 + 8742541 = 8742672
173 + 8742499 = 8742672
179 + 8742493 = 8742672
223 + 8742449 = 8742672
251 + 8742421 = 8742672
271 + 8742401 = 8742672

Showing the first eight; more decompositions exist.
