Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45178, here are decompositions:

17 + 45161 = 45178
41 + 45137 = 45178
47 + 45131 = 45178
59 + 45119 = 45178
101 + 45077 = 45178
191 + 44987 = 45178
239 + 44939 = 45178
251 + 44927 = 45178

Showing the first eight; more decompositions exist.
