Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45642, here are decompositions:

11 + 45631 = 45642
29 + 45613 = 45642
43 + 45599 = 45642
53 + 45589 = 45642
73 + 45569 = 45642
89 + 45553 = 45642
101 + 45541 = 45642
109 + 45533 = 45642

Showing the first eight; more decompositions exist.
