Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721714, here are decompositions:

13 + 8721701 = 8721714
41 + 8721673 = 8721714
47 + 8721667 = 8721714
83 + 8721631 = 8721714
97 + 8721617 = 8721714
107 + 8721607 = 8721714
173 + 8721541 = 8721714
181 + 8721533 = 8721714

Showing the first eight; more decompositions exist.
