Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712928, here are decompositions:

101 + 8712827 = 8712928
149 + 8712779 = 8712928
167 + 8712761 = 8712928
179 + 8712749 = 8712928
227 + 8712701 = 8712928
251 + 8712677 = 8712928
317 + 8712611 = 8712928
431 + 8712497 = 8712928

Showing the first eight; more decompositions exist.
