Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576876, here are decompositions:

137 + 31576739 = 31576876
167 + 31576709 = 31576876
173 + 31576703 = 31576876
257 + 31576619 = 31576876
293 + 31576583 = 31576876
347 + 31576529 = 31576876
449 + 31576427 = 31576876
467 + 31576409 = 31576876

Showing the first eight; more decompositions exist.
