Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712730, here are decompositions:

3 + 8712727 = 8712730
17 + 8712713 = 8712730
29 + 8712701 = 8712730
53 + 8712677 = 8712730
101 + 8712629 = 8712730
197 + 8712533 = 8712730
233 + 8712497 = 8712730
239 + 8712491 = 8712730

Showing the first eight; more decompositions exist.
