Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186130, here are decompositions:

11 + 186119 = 186130
17 + 186113 = 186130
23 + 186107 = 186130
59 + 186071 = 186130
89 + 186041 = 186130
107 + 186023 = 186130
137 + 185993 = 186130
173 + 185957 = 186130

Showing the first eight; more decompositions exist.
