Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67642, here are decompositions:

11 + 67631 = 67642
23 + 67619 = 67642
41 + 67601 = 67642
53 + 67589 = 67642
83 + 67559 = 67642
131 + 67511 = 67642
149 + 67493 = 67642
233 + 67409 = 67642

Showing the first eight; more decompositions exist.
