Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450834, here are decompositions:

5 + 31450829 = 31450834
11 + 31450823 = 31450834
47 + 31450787 = 31450834
53 + 31450781 = 31450834
71 + 31450763 = 31450834
113 + 31450721 = 31450834
167 + 31450667 = 31450834
251 + 31450583 = 31450834

Showing the first eight; more decompositions exist.
