Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757664, here are decompositions:

5 + 8757659 = 8757664
101 + 8757563 = 8757664
137 + 8757527 = 8757664
191 + 8757473 = 8757664
401 + 8757263 = 8757664
491 + 8757173 = 8757664
521 + 8757143 = 8757664
557 + 8757107 = 8757664

Showing the first eight; more decompositions exist.
