Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581694, here are decompositions:

7 + 581687 = 581694
11 + 581683 = 581694
31 + 581663 = 581694
37 + 581657 = 581694
97 + 581597 = 581694
137 + 581557 = 581694
167 + 581527 = 581694
173 + 581521 = 581694

Showing the first eight; more decompositions exist.
