Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502396, here are decompositions:

43 + 31502353 = 31502396
67 + 31502329 = 31502396
109 + 31502287 = 31502396
127 + 31502269 = 31502396
283 + 31502113 = 31502396
313 + 31502083 = 31502396
439 + 31501957 = 31502396
547 + 31501849 = 31502396

Showing the first eight; more decompositions exist.
