Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553052, here are decompositions:

31 + 31553021 = 31553052
53 + 31552999 = 31553052
109 + 31552943 = 31553052
173 + 31552879 = 31553052
199 + 31552853 = 31553052
331 + 31552721 = 31553052
359 + 31552693 = 31553052
409 + 31552643 = 31553052

Showing the first eight; more decompositions exist.
