Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502462, here are decompositions:

3 + 31502459 = 31502462
31 + 31502431 = 31502462
109 + 31502353 = 31502462
151 + 31502311 = 31502462
193 + 31502269 = 31502462
331 + 31502131 = 31502462
349 + 31502113 = 31502462
379 + 31502083 = 31502462

Showing the first eight; more decompositions exist.
