Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724988, here are decompositions:

5 + 8724983 = 8724988
59 + 8724929 = 8724988
269 + 8724719 = 8724988
347 + 8724641 = 8724988
491 + 8724497 = 8724988
509 + 8724479 = 8724988
521 + 8724467 = 8724988
617 + 8724371 = 8724988

Showing the first eight; more decompositions exist.
