Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712832, here are decompositions:

5 + 8712827 = 8712832
53 + 8712779 = 8712832
71 + 8712761 = 8712832
83 + 8712749 = 8712832
131 + 8712701 = 8712832
461 + 8712371 = 8712832
509 + 8712323 = 8712832
521 + 8712311 = 8712832

Showing the first eight; more decompositions exist.
