Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553150, here are decompositions:

61 + 31553089 = 31553150
73 + 31553077 = 31553150
151 + 31552999 = 31553150
271 + 31552879 = 31553150
457 + 31552693 = 31553150
547 + 31552603 = 31553150
571 + 31552579 = 31553150
613 + 31552537 = 31553150

Showing the first eight; more decompositions exist.
