Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553116, here are decompositions:

47 + 31553069 = 31553116
53 + 31553063 = 31553116
173 + 31552943 = 31553116
197 + 31552919 = 31553116
233 + 31552883 = 31553116
263 + 31552853 = 31553116
269 + 31552847 = 31553116
383 + 31552733 = 31553116

Showing the first eight; more decompositions exist.
