Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502354, here are decompositions:

43 + 31502311 = 31502354
67 + 31502287 = 31502354
193 + 31502161 = 31502354
223 + 31502131 = 31502354
241 + 31502113 = 31502354
271 + 31502083 = 31502354
397 + 31501957 = 31502354
523 + 31501831 = 31502354

Showing the first eight; more decompositions exist.
