Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553132, here are decompositions:

43 + 31553089 = 31553132
241 + 31552891 = 31553132
439 + 31552693 = 31553132
643 + 31552489 = 31553132
739 + 31552393 = 31553132
823 + 31552309 = 31553132
829 + 31552303 = 31553132
1063 + 31552069 = 31553132

Showing the first eight; more decompositions exist.
