Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581670, here are decompositions:

7 + 581663 = 581670
13 + 581657 = 581670
31 + 581639 = 581670
53 + 581617 = 581670
71 + 581599 = 581670
73 + 581597 = 581670
97 + 581573 = 581670
113 + 581557 = 581670

Showing the first eight; more decompositions exist.
