Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554746, here are decompositions:

7 + 31554739 = 31554746
37 + 31554709 = 31554746
79 + 31554667 = 31554746
109 + 31554637 = 31554746
127 + 31554619 = 31554746
163 + 31554583 = 31554746
229 + 31554517 = 31554746
283 + 31554463 = 31554746

Showing the first eight; more decompositions exist.
