Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945642, here are decompositions:

11 + 945631 = 945642
13 + 945629 = 945642
41 + 945601 = 945642
53 + 945589 = 945642
163 + 945479 = 945642
179 + 945463 = 945642
211 + 945431 = 945642
233 + 945409 = 945642

Showing the first eight; more decompositions exist.
