Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534006, here are decompositions:

47 + 31533959 = 31534006
83 + 31533923 = 31534006
167 + 31533839 = 31534006
173 + 31533833 = 31534006
233 + 31533773 = 31534006
347 + 31533659 = 31534006
419 + 31533587 = 31534006
443 + 31533563 = 31534006

Showing the first eight; more decompositions exist.
