Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742872, here are decompositions:

199 + 8742673 = 8742872
331 + 8742541 = 8742872
373 + 8742499 = 8742872
379 + 8742493 = 8742872
409 + 8742463 = 8742872
613 + 8742259 = 8742872
739 + 8742133 = 8742872
751 + 8742121 = 8742872

Showing the first eight; more decompositions exist.
