Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508994, here are decompositions:

7 + 508987 = 508994
37 + 508957 = 508994
43 + 508951 = 508994
127 + 508867 = 508994
223 + 508771 = 508994
373 + 508621 = 508994
463 + 508531 = 508994
523 + 508471 = 508994

Showing the first eight; more decompositions exist.
