Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724844, here are decompositions:

17 + 8724827 = 8724844
41 + 8724803 = 8724844
131 + 8724713 = 8724844
347 + 8724497 = 8724844
383 + 8724461 = 8724844
467 + 8724377 = 8724844
521 + 8724323 = 8724844
683 + 8724161 = 8724844

Showing the first eight; more decompositions exist.
