Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581044, here are decompositions:

3 + 581041 = 581044
47 + 580997 = 581044
131 + 580913 = 581044
173 + 580871 = 581044
251 + 580793 = 581044
257 + 580787 = 581044
281 + 580763 = 581044
311 + 580733 = 581044

Showing the first eight; more decompositions exist.
