Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554322, here are decompositions:

179 + 31554143 = 31554322
311 + 31554011 = 31554322
419 + 31553903 = 31554322
521 + 31553801 = 31554322
563 + 31553759 = 31554322
593 + 31553729 = 31554322
659 + 31553663 = 31554322
953 + 31553369 = 31554322

Showing the first eight; more decompositions exist.
