Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623322, here are decompositions:

113 + 31623209 = 31623322
149 + 31623173 = 31623322
281 + 31623041 = 31623322
383 + 31622939 = 31623322
389 + 31622933 = 31623322
593 + 31622729 = 31623322
659 + 31622663 = 31623322
743 + 31622579 = 31623322

Showing the first eight; more decompositions exist.
