Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502374, here are decompositions:

3 + 31502371 = 31502374
11 + 31502363 = 31502374
41 + 31502333 = 31502374
131 + 31502243 = 31502374
191 + 31502183 = 31502374
227 + 31502147 = 31502374
461 + 31501913 = 31502374
467 + 31501907 = 31502374

Showing the first eight; more decompositions exist.
