Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543322, here are decompositions:

79 + 31543243 = 31543322
103 + 31543219 = 31543322
313 + 31543009 = 31543322
331 + 31542991 = 31543322
373 + 31542949 = 31543322
379 + 31542943 = 31543322
523 + 31542799 = 31543322
619 + 31542703 = 31543322

Showing the first eight; more decompositions exist.
