Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554970, here are decompositions:

23 + 31554947 = 31554970
71 + 31554899 = 31554970
107 + 31554863 = 31554970
173 + 31554797 = 31554970
179 + 31554791 = 31554970
311 + 31554659 = 31554970
353 + 31554617 = 31554970
401 + 31554569 = 31554970

Showing the first eight; more decompositions exist.
