Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476876, here are decompositions:

5 + 31476871 = 31476876
23 + 31476853 = 31476876
29 + 31476847 = 31476876
47 + 31476829 = 31476876
149 + 31476727 = 31476876
173 + 31476703 = 31476876
269 + 31476607 = 31476876
283 + 31476593 = 31476876

Showing the first eight; more decompositions exist.
