Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757642, here are decompositions:

43 + 8757599 = 8757642
71 + 8757571 = 8757642
73 + 8757569 = 8757642
79 + 8757563 = 8757642
233 + 8757409 = 8757642
263 + 8757379 = 8757642
269 + 8757373 = 8757642
353 + 8757289 = 8757642

Showing the first eight; more decompositions exist.
