Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581046, here are decompositions:

5 + 581041 = 581046
17 + 581029 = 581046
107 + 580939 = 581046
127 + 580919 = 581046
157 + 580889 = 581046
233 + 580813 = 581046
239 + 580807 = 581046
283 + 580763 = 581046

Showing the first eight; more decompositions exist.
