Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724940, here are decompositions:

11 + 8724929 = 8724940
113 + 8724827 = 8724940
137 + 8724803 = 8724940
227 + 8724713 = 8724940
443 + 8724497 = 8724940
461 + 8724479 = 8724940
479 + 8724461 = 8724940
503 + 8724437 = 8724940

Showing the first eight; more decompositions exist.
