Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187026, here are decompositions:

17 + 187009 = 187026
23 + 187003 = 187026
67 + 186959 = 187026
79 + 186947 = 187026
109 + 186917 = 187026
137 + 186889 = 187026
149 + 186877 = 187026
157 + 186869 = 187026

Showing the first eight; more decompositions exist.
