Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554118, here are decompositions:

41 + 31554077 = 31554118
107 + 31554011 = 31554118
131 + 31553987 = 31554118
251 + 31553867 = 31554118
311 + 31553807 = 31554118
317 + 31553801 = 31554118
359 + 31553759 = 31554118
389 + 31553729 = 31554118

Showing the first eight; more decompositions exist.
