Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151422, here are decompositions:

31 + 151391 = 151422
41 + 151381 = 151422
43 + 151379 = 151422
79 + 151343 = 151422
83 + 151339 = 151422
149 + 151273 = 151422
179 + 151243 = 151422
181 + 151241 = 151422

Showing the first eight; more decompositions exist.
