Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626322, here are decompositions:

89 + 31626233 = 31626322
113 + 31626209 = 31626322
131 + 31626191 = 31626322
191 + 31626131 = 31626322
269 + 31626053 = 31626322
281 + 31626041 = 31626322
311 + 31626011 = 31626322
353 + 31625969 = 31626322

Showing the first eight; more decompositions exist.
