Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554316, here are decompositions:

29 + 31554287 = 31554316
137 + 31554179 = 31554316
173 + 31554143 = 31554316
239 + 31554077 = 31554316
449 + 31553867 = 31554316
509 + 31553807 = 31554316
557 + 31553759 = 31554316
587 + 31553729 = 31554316

Showing the first eight; more decompositions exist.
