Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724994, here are decompositions:

11 + 8724983 = 8724994
167 + 8724827 = 8724994
191 + 8724803 = 8724994
281 + 8724713 = 8724994
353 + 8724641 = 8724994
557 + 8724437 = 8724994
617 + 8724377 = 8724994
647 + 8724347 = 8724994

Showing the first eight; more decompositions exist.
