Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456876, here are decompositions:

47 + 31456829 = 31456876
89 + 31456787 = 31456876
107 + 31456769 = 31456876
137 + 31456739 = 31456876
149 + 31456727 = 31456876
173 + 31456703 = 31456876
197 + 31456679 = 31456876
359 + 31456517 = 31456876

Showing the first eight; more decompositions exist.
