Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45198, here are decompositions:

7 + 45191 = 45198
17 + 45181 = 45198
19 + 45179 = 45198
37 + 45161 = 45198
59 + 45139 = 45198
61 + 45137 = 45198
67 + 45131 = 45198
71 + 45127 = 45198

Showing the first eight; more decompositions exist.
