Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508386, here are decompositions:

13 + 508373 = 508386
19 + 508367 = 508386
23 + 508363 = 508386
37 + 508349 = 508386
59 + 508327 = 508386
89 + 508297 = 508386
113 + 508273 = 508386
127 + 508259 = 508386

Showing the first eight; more decompositions exist.
