Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722748, here are decompositions:

37 + 8722711 = 8722748
127 + 8722621 = 8722748
271 + 8722477 = 8722748
277 + 8722471 = 8722748
409 + 8722339 = 8722748
457 + 8722291 = 8722748
577 + 8722171 = 8722748
631 + 8722117 = 8722748

Showing the first eight; more decompositions exist.
