Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951642, here are decompositions:

5 + 951637 = 951642
19 + 951623 = 951642
53 + 951589 = 951642
59 + 951583 = 951642
61 + 951581 = 951642
71 + 951571 = 951642
89 + 951553 = 951642
151 + 951491 = 951642

Showing the first eight; more decompositions exist.
