Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450876, here are decompositions:

29 + 31450847 = 31450876
47 + 31450829 = 31450876
53 + 31450823 = 31450876
89 + 31450787 = 31450876
113 + 31450763 = 31450876
137 + 31450739 = 31450876
257 + 31450619 = 31450876
263 + 31450613 = 31450876

Showing the first eight; more decompositions exist.
