Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494322, here are decompositions:

29 + 31494293 = 31494322
59 + 31494263 = 31494322
179 + 31494143 = 31494322
239 + 31494083 = 31494322
269 + 31494053 = 31494322
281 + 31494041 = 31494322
809 + 31493513 = 31494322
983 + 31493339 = 31494322

Showing the first eight; more decompositions exist.
