Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508644, here are decompositions:

7 + 508637 = 508644
23 + 508621 = 508644
61 + 508583 = 508644
67 + 508577 = 508644
113 + 508531 = 508644
127 + 508517 = 508644
131 + 508513 = 508644
167 + 508477 = 508644

Showing the first eight; more decompositions exist.
