Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712862, here are decompositions:

3 + 8712859 = 8712862
83 + 8712779 = 8712862
101 + 8712761 = 8712862
113 + 8712749 = 8712862
149 + 8712713 = 8712862
233 + 8712629 = 8712862
251 + 8712611 = 8712862
491 + 8712371 = 8712862

Showing the first eight; more decompositions exist.
