Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45442, here are decompositions:

3 + 45439 = 45442
29 + 45413 = 45442
53 + 45389 = 45442
101 + 45341 = 45442
113 + 45329 = 45442
149 + 45293 = 45442
179 + 45263 = 45442
251 + 45191 = 45442

Showing the first eight; more decompositions exist.
