Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502294, here are decompositions:

7 + 31502287 = 31502294
163 + 31502131 = 31502294
181 + 31502113 = 31502294
211 + 31502083 = 31502294
337 + 31501957 = 31502294
433 + 31501861 = 31502294
463 + 31501831 = 31502294
487 + 31501807 = 31502294

Showing the first eight; more decompositions exist.
