Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45238, here are decompositions:

5 + 45233 = 45238
41 + 45197 = 45238
47 + 45191 = 45238
59 + 45179 = 45238
101 + 45137 = 45238
107 + 45131 = 45238
251 + 44987 = 45238
311 + 44927 = 45238

Showing the first eight; more decompositions exist.
