Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506490, here are decompositions:

11 + 506479 = 506490
29 + 506461 = 506490
31 + 506459 = 506490
41 + 506449 = 506490
67 + 506423 = 506490
73 + 506417 = 506490
97 + 506393 = 506490
109 + 506381 = 506490

Showing the first eight; more decompositions exist.
