Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521090, here are decompositions:

43 + 521047 = 521090
67 + 521023 = 521090
109 + 520981 = 521090
127 + 520963 = 521090
223 + 520867 = 521090
277 + 520813 = 521090
331 + 520759 = 521090
373 + 520717 = 521090

Showing the first eight; more decompositions exist.
