Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540086, here are decompositions:

23 + 31540063 = 31540086
73 + 31540013 = 31540086
79 + 31540007 = 31540086
197 + 31539889 = 31540086
223 + 31539863 = 31540086
229 + 31539857 = 31540086
269 + 31539817 = 31540086
349 + 31539737 = 31540086

Showing the first eight; more decompositions exist.
