Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45408, here are decompositions:

5 + 45403 = 45408
19 + 45389 = 45408
31 + 45377 = 45408
47 + 45361 = 45408
67 + 45341 = 45408
71 + 45337 = 45408
79 + 45329 = 45408
89 + 45319 = 45408

Showing the first eight; more decompositions exist.
