Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581056, here are decompositions:

59 + 580997 = 581056
137 + 580919 = 581056
167 + 580889 = 581056
197 + 580859 = 581056
263 + 580793 = 581056
269 + 580787 = 581056
293 + 580763 = 581056
383 + 580673 = 581056

Showing the first eight; more decompositions exist.
