Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712906, here are decompositions:

43 + 8712863 = 8712906
47 + 8712859 = 8712906
79 + 8712827 = 8712906
113 + 8712793 = 8712906
127 + 8712779 = 8712906
149 + 8712757 = 8712906
157 + 8712749 = 8712906
179 + 8712727 = 8712906

Showing the first eight; more decompositions exist.
