Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553468, here are decompositions:

109 + 31553359 = 31553468
307 + 31553161 = 31553468
379 + 31553089 = 31553468
577 + 31552891 = 31553468
787 + 31552681 = 31553468
829 + 31552639 = 31553468
1039 + 31552429 = 31553468
1117 + 31552351 = 31553468

Showing the first eight; more decompositions exist.
