Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009540, here are decompositions:

3 + 1009537 = 1009540
41 + 1009499 = 1009540
53 + 1009487 = 1009540
83 + 1009457 = 1009540
101 + 1009439 = 1009540
107 + 1009433 = 1009540
167 + 1009373 = 1009540
179 + 1009361 = 1009540

Showing the first eight; more decompositions exist.
