Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508780, here are decompositions:

53 + 508727 = 508780
71 + 508709 = 508780
137 + 508643 = 508780
197 + 508583 = 508780
263 + 508517 = 508780
281 + 508499 = 508780
347 + 508433 = 508780
431 + 508349 = 508780

Showing the first eight; more decompositions exist.
