Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540036, here are decompositions:

5 + 31540031 = 31540036
23 + 31540013 = 31540036
29 + 31540007 = 31540036
173 + 31539863 = 31540036
179 + 31539857 = 31540036
197 + 31539839 = 31540036
443 + 31539593 = 31540036
449 + 31539587 = 31540036

Showing the first eight; more decompositions exist.
