Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581006, here are decompositions:

37 + 580969 = 581006
67 + 580939 = 581006
79 + 580927 = 581006
163 + 580843 = 581006
193 + 580813 = 581006
199 + 580807 = 581006
313 + 580693 = 581006
367 + 580639 = 581006

Showing the first eight; more decompositions exist.
