Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603054, here are decompositions:

137 + 31602917 = 31603054
191 + 31602863 = 31603054
251 + 31602803 = 31603054
467 + 31602587 = 31603054
557 + 31602497 = 31603054
653 + 31602401 = 31603054
701 + 31602353 = 31603054
773 + 31602281 = 31603054

Showing the first eight; more decompositions exist.
