Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485052, here are decompositions:

3 + 31485049 = 31485052
29 + 31485023 = 31485052
59 + 31484993 = 31485052
149 + 31484903 = 31485052
251 + 31484801 = 31485052
281 + 31484771 = 31485052
311 + 31484741 = 31485052
353 + 31484699 = 31485052

Showing the first eight; more decompositions exist.
