Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468180, here are decompositions:

7 + 468173 = 468180
23 + 468157 = 468180
29 + 468151 = 468180
43 + 468137 = 468180
47 + 468133 = 468180
59 + 468121 = 468180
67 + 468113 = 468180
71 + 468109 = 468180

Showing the first eight; more decompositions exist.
