Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505642, here are decompositions:

3 + 505639 = 505642
23 + 505619 = 505642
29 + 505613 = 505642
41 + 505601 = 505642
83 + 505559 = 505642
131 + 505511 = 505642
149 + 505493 = 505642
173 + 505469 = 505642

Showing the first eight; more decompositions exist.
