Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722738, here are decompositions:

107 + 8722631 = 8722738
131 + 8722607 = 8722738
197 + 8722541 = 8722738
239 + 8722499 = 8722738
347 + 8722391 = 8722738
569 + 8722169 = 8722738
641 + 8722097 = 8722738
659 + 8722079 = 8722738

Showing the first eight; more decompositions exist.
