Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712870, here are decompositions:

7 + 8712863 = 8712870
11 + 8712859 = 8712870
43 + 8712827 = 8712870
109 + 8712761 = 8712870
113 + 8712757 = 8712870
157 + 8712713 = 8712870
193 + 8712677 = 8712870
241 + 8712629 = 8712870

Showing the first eight; more decompositions exist.
