Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757988, here are decompositions:

131 + 8757857 = 8757988
137 + 8757851 = 8757988
167 + 8757821 = 8757988
179 + 8757809 = 8757988
269 + 8757719 = 8757988
389 + 8757599 = 8757988
419 + 8757569 = 8757988
461 + 8757527 = 8757988

Showing the first eight; more decompositions exist.
