Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581674, here are decompositions:

11 + 581663 = 581674
17 + 581657 = 581674
101 + 581573 = 581674
227 + 581447 = 581674
263 + 581411 = 581674
281 + 581393 = 581674
491 + 581183 = 581674
503 + 581171 = 581674

Showing the first eight; more decompositions exist.
