Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649964, here are decompositions:

53 + 8649911 = 8649964
83 + 8649881 = 8649964
107 + 8649857 = 8649964
173 + 8649791 = 8649964
293 + 8649671 = 8649964
353 + 8649611 = 8649964
383 + 8649581 = 8649964
431 + 8649533 = 8649964

Showing the first eight; more decompositions exist.
