Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544222, here are decompositions:

43 + 31544179 = 31544222
181 + 31544041 = 31544222
211 + 31544011 = 31544222
349 + 31543873 = 31544222
379 + 31543843 = 31544222
439 + 31543783 = 31544222
499 + 31543723 = 31544222
643 + 31543579 = 31544222

Showing the first eight; more decompositions exist.
