Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502936, here are decompositions:

13 + 31502923 = 31502936
79 + 31502857 = 31502936
193 + 31502743 = 31502936
277 + 31502659 = 31502936
349 + 31502587 = 31502936
373 + 31502563 = 31502936
379 + 31502557 = 31502936
397 + 31502539 = 31502936

Showing the first eight; more decompositions exist.
