Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581074, here are decompositions:

3 + 581071 = 581074
5 + 581069 = 581074
173 + 580901 = 581074
281 + 580793 = 581074
311 + 580763 = 581074
317 + 580757 = 581074
383 + 580691 = 581074
401 + 580673 = 581074

Showing the first eight; more decompositions exist.
