Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757726, here are decompositions:

7 + 8757719 = 8757726
13 + 8757713 = 8757726
67 + 8757659 = 8757726
83 + 8757643 = 8757726
127 + 8757599 = 8757726
157 + 8757569 = 8757726
163 + 8757563 = 8757726
199 + 8757527 = 8757726

Showing the first eight; more decompositions exist.
