Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151190, here are decompositions:

19 + 151171 = 151190
37 + 151153 = 151190
139 + 151051 = 151190
163 + 151027 = 151190
181 + 151009 = 151190
199 + 150991 = 151190
211 + 150979 = 151190
223 + 150967 = 151190

Showing the first eight; more decompositions exist.
