Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758540, here are decompositions:

3 + 8758537 = 8758540
29 + 8758511 = 8758540
41 + 8758499 = 8758540
59 + 8758481 = 8758540
83 + 8758457 = 8758540
107 + 8758433 = 8758540
113 + 8758427 = 8758540
149 + 8758391 = 8758540

Showing the first eight; more decompositions exist.
