Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708090, here are decompositions:

3 + 8708087 = 8708090
19 + 8708071 = 8708090
73 + 8708017 = 8708090
151 + 8707939 = 8708090
211 + 8707879 = 8708090
229 + 8707861 = 8708090
337 + 8707753 = 8708090
379 + 8707711 = 8708090

Showing the first eight; more decompositions exist.
