Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538876, here are decompositions:

97 + 31538779 = 31538876
157 + 31538719 = 31538876
163 + 31538713 = 31538876
223 + 31538653 = 31538876
307 + 31538569 = 31538876
337 + 31538539 = 31538876
349 + 31538527 = 31538876
373 + 31538503 = 31538876

Showing the first eight; more decompositions exist.
