Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712806, here are decompositions:

13 + 8712793 = 8712806
79 + 8712727 = 8712806
97 + 8712709 = 8712806
229 + 8712577 = 8712806
283 + 8712523 = 8712806
409 + 8712397 = 8712806
433 + 8712373 = 8712806
439 + 8712367 = 8712806

Showing the first eight; more decompositions exist.
