Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756730, here are decompositions:

23 + 8756707 = 8756730
41 + 8756689 = 8756730
43 + 8756687 = 8756730
53 + 8756677 = 8756730
61 + 8756669 = 8756730
71 + 8756659 = 8756730
97 + 8756633 = 8756730
107 + 8756623 = 8756730

Showing the first eight; more decompositions exist.
