Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540006, here are decompositions:

149 + 31539857 = 31540006
167 + 31539839 = 31540006
269 + 31539737 = 31540006
293 + 31539713 = 31540006
347 + 31539659 = 31540006
419 + 31539587 = 31540006
593 + 31539413 = 31540006
653 + 31539353 = 31540006

Showing the first eight; more decompositions exist.
