Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187230, here are decompositions:

7 + 187223 = 187230
11 + 187219 = 187230
13 + 187217 = 187230
19 + 187211 = 187230
37 + 187193 = 187230
41 + 187189 = 187230
53 + 187177 = 187230
59 + 187171 = 187230

Showing the first eight; more decompositions exist.
