Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45438, here are decompositions:

5 + 45433 = 45438
11 + 45427 = 45438
61 + 45377 = 45438
97 + 45341 = 45438
101 + 45337 = 45438
109 + 45329 = 45438
131 + 45307 = 45438
149 + 45289 = 45438

Showing the first eight; more decompositions exist.
