Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45420, here are decompositions:

7 + 45413 = 45420
17 + 45403 = 45420
31 + 45389 = 45420
43 + 45377 = 45420
59 + 45361 = 45420
79 + 45341 = 45420
83 + 45337 = 45420
101 + 45319 = 45420

Showing the first eight; more decompositions exist.
