Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185226, here are decompositions:

5 + 185221 = 185226
37 + 185189 = 185226
43 + 185183 = 185226
59 + 185167 = 185226
73 + 185153 = 185226
89 + 185137 = 185226
103 + 185123 = 185226
127 + 185099 = 185226

Showing the first eight; more decompositions exist.
