Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505488, here are decompositions:

7 + 505481 = 505488
19 + 505469 = 505488
29 + 505459 = 505488
41 + 505447 = 505488
59 + 505429 = 505488
79 + 505409 = 505488
89 + 505399 = 505488
131 + 505357 = 505488

Showing the first eight; more decompositions exist.
