Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45378, here are decompositions:

17 + 45361 = 45378
37 + 45341 = 45378
41 + 45337 = 45378
59 + 45319 = 45378
61 + 45317 = 45378
71 + 45307 = 45378
89 + 45289 = 45378
97 + 45281 = 45378

Showing the first eight; more decompositions exist.
