Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485536, here are decompositions:

3 + 31485533 = 31485536
109 + 31485427 = 31485536
139 + 31485397 = 31485536
157 + 31485379 = 31485536
223 + 31485313 = 31485536
457 + 31485079 = 31485536
487 + 31485049 = 31485536
547 + 31484989 = 31485536

Showing the first eight; more decompositions exist.
