Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981526, here are decompositions:

3 + 981523 = 981526
53 + 981473 = 981526
59 + 981467 = 981526
83 + 981443 = 981526
89 + 981437 = 981526
107 + 981419 = 981526
149 + 981377 = 981526
239 + 981287 = 981526

Showing the first eight; more decompositions exist.
