Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553318, here are decompositions:

157 + 31553161 = 31553318
229 + 31553089 = 31553318
241 + 31553077 = 31553318
439 + 31552879 = 31553318
487 + 31552831 = 31553318
571 + 31552747 = 31553318
739 + 31552579 = 31553318
829 + 31552489 = 31553318

Showing the first eight; more decompositions exist.
