Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544072, here are decompositions:

19 + 31544053 = 31544072
31 + 31544041 = 31544072
61 + 31544011 = 31544072
199 + 31543873 = 31544072
229 + 31543843 = 31544072
349 + 31543723 = 31544072
541 + 31543531 = 31544072
619 + 31543453 = 31544072

Showing the first eight; more decompositions exist.
