Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724898, here are decompositions:

71 + 8724827 = 8724898
179 + 8724719 = 8724898
257 + 8724641 = 8724898
401 + 8724497 = 8724898
419 + 8724479 = 8724898
431 + 8724467 = 8724898
461 + 8724437 = 8724898
521 + 8724377 = 8724898

Showing the first eight; more decompositions exist.
