Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45390, here are decompositions:

13 + 45377 = 45390
29 + 45361 = 45390
47 + 45343 = 45390
53 + 45337 = 45390
61 + 45329 = 45390
71 + 45319 = 45390
73 + 45317 = 45390
83 + 45307 = 45390

Showing the first eight; more decompositions exist.
