Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187186, here are decompositions:

5 + 187181 = 187186
23 + 187163 = 187186
47 + 187139 = 187186
53 + 187133 = 187186
59 + 187127 = 187186
113 + 187073 = 187186
137 + 187049 = 187186
227 + 186959 = 187186

Showing the first eight; more decompositions exist.
