Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505590, here are decompositions:

17 + 505573 = 505590
31 + 505559 = 505590
53 + 505537 = 505590
67 + 505523 = 505590
79 + 505511 = 505590
89 + 505501 = 505590
97 + 505493 = 505590
109 + 505481 = 505590

Showing the first eight; more decompositions exist.
