Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502282, here are decompositions:

3 + 31502279 = 31502282
13 + 31502269 = 31502282
151 + 31502131 = 31502282
199 + 31502083 = 31502282
421 + 31501861 = 31502282
433 + 31501849 = 31502282
463 + 31501819 = 31502282
523 + 31501759 = 31502282

Showing the first eight; more decompositions exist.
