Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468540, here are decompositions:

13 + 468527 = 468540
31 + 468509 = 468540
41 + 468499 = 468540
47 + 468493 = 468540
67 + 468473 = 468540
89 + 468451 = 468540
101 + 468439 = 468540
151 + 468389 = 468540

Showing the first eight; more decompositions exist.
