Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742472, here are decompositions:

3 + 8742469 = 8742472
23 + 8742449 = 8742472
71 + 8742401 = 8742472
113 + 8742359 = 8742472
311 + 8742161 = 8742472
461 + 8742011 = 8742472
521 + 8741951 = 8742472
659 + 8741813 = 8742472

Showing the first eight; more decompositions exist.
