Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187070, here are decompositions:

3 + 187067 = 187070
43 + 187027 = 187070
61 + 187009 = 187070
67 + 187003 = 187070
181 + 186889 = 187070
193 + 186877 = 187070
199 + 186871 = 187070
211 + 186859 = 187070

Showing the first eight; more decompositions exist.
