Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123490, here are decompositions:

11 + 123479 = 123490
41 + 123449 = 123490
71 + 123419 = 123490
83 + 123407 = 123490
89 + 123401 = 123490
113 + 123377 = 123490
149 + 123341 = 123490
167 + 123323 = 123490

Showing the first eight; more decompositions exist.
