Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757756, here are decompositions:

37 + 8757719 = 8757756
43 + 8757713 = 8757756
97 + 8757659 = 8757756
113 + 8757643 = 8757756
157 + 8757599 = 8757756
193 + 8757563 = 8757756
229 + 8757527 = 8757756
233 + 8757523 = 8757756

Showing the first eight; more decompositions exist.
