Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712828, here are decompositions:

67 + 8712761 = 8712828
71 + 8712757 = 8712828
79 + 8712749 = 8712828
101 + 8712727 = 8712828
127 + 8712701 = 8712828
151 + 8712677 = 8712828
167 + 8712661 = 8712828
199 + 8712629 = 8712828

Showing the first eight; more decompositions exist.
