Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543622, here are decompositions:

43 + 31543579 = 31543622
79 + 31543543 = 31543622
193 + 31543429 = 31543622
349 + 31543273 = 31543622
379 + 31543243 = 31543622
613 + 31543009 = 31543622
631 + 31542991 = 31543622
673 + 31542949 = 31543622

Showing the first eight; more decompositions exist.
