Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554876, here are decompositions:

13 + 31554863 = 31554876
47 + 31554829 = 31554876
53 + 31554823 = 31554876
79 + 31554797 = 31554876
127 + 31554749 = 31554876
137 + 31554739 = 31554876
167 + 31554709 = 31554876
239 + 31554637 = 31554876

Showing the first eight; more decompositions exist.
