Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508786, here are decompositions:

59 + 508727 = 508786
149 + 508637 = 508786
167 + 508619 = 508786
227 + 508559 = 508786
269 + 508517 = 508786
347 + 508439 = 508786
353 + 508433 = 508786
419 + 508367 = 508786

Showing the first eight; more decompositions exist.
