Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502606, here are decompositions:

19 + 31502587 = 31502606
43 + 31502563 = 31502606
67 + 31502539 = 31502606
73 + 31502533 = 31502606
277 + 31502329 = 31502606
337 + 31502269 = 31502606
523 + 31502083 = 31502606
727 + 31501879 = 31502606

Showing the first eight; more decompositions exist.
