Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581002, here are decompositions:

5 + 580997 = 581002
83 + 580919 = 581002
89 + 580913 = 581002
101 + 580901 = 581002
113 + 580889 = 581002
131 + 580871 = 581002
239 + 580763 = 581002
269 + 580733 = 581002

Showing the first eight; more decompositions exist.
