Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749718, here are decompositions:

67 + 8749651 = 8749718
139 + 8749579 = 8749718
409 + 8749309 = 8749718
499 + 8749219 = 8749718
577 + 8749141 = 8749718
631 + 8749087 = 8749718
727 + 8748991 = 8749718
739 + 8748979 = 8749718

Showing the first eight; more decompositions exist.
