Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721654, here are decompositions:

23 + 8721631 = 8721654
37 + 8721617 = 8721654
47 + 8721607 = 8721654
113 + 8721541 = 8721654
167 + 8721487 = 8721654
173 + 8721481 = 8721654
181 + 8721473 = 8721654
211 + 8721443 = 8721654

Showing the first eight; more decompositions exist.
