Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540246, here are decompositions:

5 + 31540241 = 31540246
29 + 31540217 = 31540246
83 + 31540163 = 31540246
137 + 31540109 = 31540246
233 + 31540013 = 31540246
239 + 31540007 = 31540246
383 + 31539863 = 31540246
389 + 31539857 = 31540246

Showing the first eight; more decompositions exist.
