Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468640, here are decompositions:

17 + 468623 = 468640
41 + 468599 = 468640
47 + 468593 = 468640
59 + 468581 = 468640
83 + 468557 = 468640
89 + 468551 = 468640
113 + 468527 = 468640
131 + 468509 = 468640

Showing the first eight; more decompositions exist.
