Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494664, here are decompositions:

53 + 31494611 = 31494664
83 + 31494581 = 31494664
167 + 31494497 = 31494664
197 + 31494467 = 31494664
233 + 31494431 = 31494664
263 + 31494401 = 31494664
317 + 31494347 = 31494664
401 + 31494263 = 31494664

Showing the first eight; more decompositions exist.
