Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757648, here are decompositions:

5 + 8757643 = 8757648
79 + 8757569 = 8757648
131 + 8757517 = 8757648
239 + 8757409 = 8757648
269 + 8757379 = 8757648
271 + 8757377 = 8757648
307 + 8757341 = 8757648
359 + 8757289 = 8757648

Showing the first eight; more decompositions exist.
