Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447322, here are decompositions:

223 + 31447099 = 31447322
241 + 31447081 = 31447322
349 + 31446973 = 31447322
373 + 31446949 = 31447322
463 + 31446859 = 31447322
769 + 31446553 = 31447322
883 + 31446439 = 31447322
1069 + 31446253 = 31447322

Showing the first eight; more decompositions exist.
