Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502514, here are decompositions:

31 + 31502483 = 31502514
73 + 31502441 = 31502514
83 + 31502431 = 31502514
151 + 31502363 = 31502514
181 + 31502333 = 31502514
227 + 31502287 = 31502514
271 + 31502243 = 31502514
331 + 31502183 = 31502514

Showing the first eight; more decompositions exist.
