Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698720, here are decompositions:

47 + 8698673 = 8698720
167 + 8698553 = 8698720
227 + 8698493 = 8698720
263 + 8698457 = 8698720
269 + 8698451 = 8698720
467 + 8698253 = 8698720
479 + 8698241 = 8698720
491 + 8698229 = 8698720

Showing the first eight; more decompositions exist.
