Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502488, here are decompositions:

5 + 31502483 = 31502488
29 + 31502459 = 31502488
47 + 31502441 = 31502488
359 + 31502129 = 31502488
389 + 31502099 = 31502488
509 + 31501979 = 31502488
761 + 31501727 = 31502488
827 + 31501661 = 31502488

Showing the first eight; more decompositions exist.
