Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554274, here are decompositions:

113 + 31554161 = 31554274
131 + 31554143 = 31554274
197 + 31554077 = 31554274
263 + 31554011 = 31554274
281 + 31553993 = 31554274
467 + 31553807 = 31554274
491 + 31553783 = 31554274
821 + 31553453 = 31554274

Showing the first eight; more decompositions exist.
