Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506642, here are decompositions:

13 + 506629 = 506642
43 + 506599 = 506642
79 + 506563 = 506642
109 + 506533 = 506642
151 + 506491 = 506642
163 + 506479 = 506642
181 + 506461 = 506642
193 + 506449 = 506642

Showing the first eight; more decompositions exist.
