Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540016, here are decompositions:

3 + 31540013 = 31540016
7 + 31540009 = 31540016
127 + 31539889 = 31540016
199 + 31539817 = 31540016
367 + 31539649 = 31540016
373 + 31539643 = 31540016
433 + 31539583 = 31540016
577 + 31539439 = 31540016

Showing the first eight; more decompositions exist.
