Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012540, here are decompositions:

17 + 1012523 = 1012540
59 + 1012481 = 1012540
83 + 1012457 = 1012540
101 + 1012439 = 1012540
107 + 1012433 = 1012540
167 + 1012373 = 1012540
233 + 1012307 = 1012540
251 + 1012289 = 1012540

Showing the first eight; more decompositions exist.
