Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951620, here are decompositions:

31 + 951589 = 951620
37 + 951583 = 951620
67 + 951553 = 951620
151 + 951469 = 951620
193 + 951427 = 951620
277 + 951343 = 951620
337 + 951283 = 951620
541 + 951079 = 951620

Showing the first eight; more decompositions exist.
