Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670664, here are decompositions:

11 + 8670653 = 8670664
53 + 8670611 = 8670664
113 + 8670551 = 8670664
131 + 8670533 = 8670664
173 + 8670491 = 8670664
257 + 8670407 = 8670664
293 + 8670371 = 8670664
311 + 8670353 = 8670664

Showing the first eight; more decompositions exist.
