Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581718, here are decompositions:

17 + 581701 = 581718
19 + 581699 = 581718
31 + 581687 = 581718
61 + 581657 = 581718
79 + 581639 = 581718
101 + 581617 = 581718
167 + 581551 = 581718
191 + 581527 = 581718

Showing the first eight; more decompositions exist.
