Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724958, here are decompositions:

29 + 8724929 = 8724958
131 + 8724827 = 8724958
239 + 8724719 = 8724958
317 + 8724641 = 8724958
461 + 8724497 = 8724958
479 + 8724479 = 8724958
491 + 8724467 = 8724958
521 + 8724437 = 8724958

Showing the first eight; more decompositions exist.
