Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581708, here are decompositions:

7 + 581701 = 581708
109 + 581599 = 581708
151 + 581557 = 581708
157 + 581551 = 581708
181 + 581527 = 581708
331 + 581377 = 581708
367 + 581341 = 581708
397 + 581311 = 581708

Showing the first eight; more decompositions exist.
