Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508490, here are decompositions:

13 + 508477 = 508490
19 + 508471 = 508490
97 + 508393 = 508490
127 + 508363 = 508490
163 + 508327 = 508490
193 + 508297 = 508490
277 + 508213 = 508490
331 + 508159 = 508490

Showing the first eight; more decompositions exist.
