Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534408, here are decompositions:

107 + 31534301 = 31534408
137 + 31534271 = 31534408
167 + 31534241 = 31534408
239 + 31534169 = 31534408
449 + 31533959 = 31534408
569 + 31533839 = 31534408
617 + 31533791 = 31534408
701 + 31533707 = 31534408

Showing the first eight; more decompositions exist.
