Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748664, here are decompositions:

11 + 8748653 = 8748664
17 + 8748647 = 8748664
83 + 8748581 = 8748664
101 + 8748563 = 8748664
191 + 8748473 = 8748664
233 + 8748431 = 8748664
251 + 8748413 = 8748664
383 + 8748281 = 8748664

Showing the first eight; more decompositions exist.
