Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453966, here are decompositions:

23 + 31453943 = 31453966
83 + 31453883 = 31453966
233 + 31453733 = 31453966
239 + 31453727 = 31453966
389 + 31453577 = 31453966
443 + 31453523 = 31453966
503 + 31453463 = 31453966
683 + 31453283 = 31453966

Showing the first eight; more decompositions exist.
