Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554694, here are decompositions:

23 + 31554671 = 31554694
53 + 31554641 = 31554694
167 + 31554527 = 31554694
293 + 31554401 = 31554694
617 + 31554077 = 31554694
683 + 31554011 = 31554694
701 + 31553993 = 31554694
827 + 31553867 = 31554694

Showing the first eight; more decompositions exist.
