Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554106, here are decompositions:

29 + 31554077 = 31554106
113 + 31553993 = 31554106
239 + 31553867 = 31554106
347 + 31553759 = 31554106
443 + 31553663 = 31554106
587 + 31553519 = 31554106
653 + 31553453 = 31554106
719 + 31553387 = 31554106

Showing the first eight; more decompositions exist.
