Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739664, here are decompositions:

41 + 8739623 = 8739664
47 + 8739617 = 8739664
173 + 8739491 = 8739664
233 + 8739431 = 8739664
383 + 8739281 = 8739664
467 + 8739197 = 8739664
641 + 8739023 = 8739664
701 + 8738963 = 8739664

Showing the first eight; more decompositions exist.
