Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462322, here are decompositions:

181 + 31462141 = 31462322
373 + 31461949 = 31462322
379 + 31461943 = 31462322
499 + 31461823 = 31462322
751 + 31461571 = 31462322
769 + 31461553 = 31462322
919 + 31461403 = 31462322
1021 + 31461301 = 31462322

Showing the first eight; more decompositions exist.
