Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665964, here are decompositions:

31 + 8665933 = 8665964
67 + 8665897 = 8665964
313 + 8665651 = 8665964
331 + 8665633 = 8665964
397 + 8665567 = 8665964
421 + 8665543 = 8665964
523 + 8665441 = 8665964
607 + 8665357 = 8665964

Showing the first eight; more decompositions exist.
