Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554964, here are decompositions:

3 + 31554961 = 31554964
17 + 31554947 = 31554964
71 + 31554893 = 31554964
101 + 31554863 = 31554964
113 + 31554851 = 31554964
167 + 31554797 = 31554964
173 + 31554791 = 31554964
293 + 31554671 = 31554964

Showing the first eight; more decompositions exist.
