Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554736, here are decompositions:

167 + 31554569 = 31554736
197 + 31554539 = 31554736
263 + 31554473 = 31554736
449 + 31554287 = 31554736
557 + 31554179 = 31554736
593 + 31554143 = 31554736
659 + 31554077 = 31554736
743 + 31553993 = 31554736

Showing the first eight; more decompositions exist.
