Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757540, here are decompositions:

13 + 8757527 = 8757540
17 + 8757523 = 8757540
23 + 8757517 = 8757540
53 + 8757487 = 8757540
67 + 8757473 = 8757540
131 + 8757409 = 8757540
151 + 8757389 = 8757540
163 + 8757377 = 8757540

Showing the first eight; more decompositions exist.
