Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690164, here are decompositions:

47 + 8690117 = 8690164
71 + 8690093 = 8690164
101 + 8690063 = 8690164
167 + 8689997 = 8690164
311 + 8689853 = 8690164
347 + 8689817 = 8690164
491 + 8689673 = 8690164
503 + 8689661 = 8690164

Showing the first eight; more decompositions exist.
