Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45480, here are decompositions:

41 + 45439 = 45480
47 + 45433 = 45480
53 + 45427 = 45480
67 + 45413 = 45480
103 + 45377 = 45480
137 + 45343 = 45480
139 + 45341 = 45480
151 + 45329 = 45480

Showing the first eight; more decompositions exist.
