Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759490, here are decompositions:

23 + 8759467 = 8759490
31 + 8759459 = 8759490
67 + 8759423 = 8759490
71 + 8759419 = 8759490
83 + 8759407 = 8759490
97 + 8759393 = 8759490
137 + 8759353 = 8759490
139 + 8759351 = 8759490

Showing the first eight; more decompositions exist.
