Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742624, here are decompositions:

47 + 8742577 = 8742624
53 + 8742571 = 8742624
73 + 8742551 = 8742624
83 + 8742541 = 8742624
113 + 8742511 = 8742624
127 + 8742497 = 8742624
131 + 8742493 = 8742624
223 + 8742401 = 8742624

Showing the first eight; more decompositions exist.
