Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45432, here are decompositions:

5 + 45427 = 45432
19 + 45413 = 45432
29 + 45403 = 45432
43 + 45389 = 45432
71 + 45361 = 45432
89 + 45343 = 45432
103 + 45329 = 45432
113 + 45319 = 45432

Showing the first eight; more decompositions exist.
