Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554984, here are decompositions:

23 + 31554961 = 31554984
37 + 31554947 = 31554984
101 + 31554883 = 31554984
173 + 31554811 = 31554984
193 + 31554791 = 31554984
313 + 31554671 = 31554984
317 + 31554667 = 31554984
347 + 31554637 = 31554984

Showing the first eight; more decompositions exist.
