Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561490, here are decompositions:

29 + 561461 = 561490
71 + 561419 = 561490
101 + 561389 = 561490
113 + 561377 = 561490
131 + 561359 = 561490
239 + 561251 = 561490
317 + 561173 = 561490
389 + 561101 = 561490

Showing the first eight; more decompositions exist.
