Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668316, here are decompositions:

37 + 8668279 = 8668316
43 + 8668273 = 8668316
109 + 8668207 = 8668316
337 + 8667979 = 8668316
367 + 8667949 = 8668316
409 + 8667907 = 8668316
487 + 8667829 = 8668316
523 + 8667793 = 8668316

Showing the first eight; more decompositions exist.
