Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704228, here are decompositions:

59 + 8704169 = 8704228
107 + 8704121 = 8704228
179 + 8704049 = 8704228
257 + 8703971 = 8704228
317 + 8703911 = 8704228
509 + 8703719 = 8704228
569 + 8703659 = 8704228
587 + 8703641 = 8704228

Showing the first eight; more decompositions exist.
