Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534834, here are decompositions:

3 + 31534831 = 31534834
47 + 31534787 = 31534834
83 + 31534751 = 31534834
197 + 31534637 = 31534834
281 + 31534553 = 31534834
347 + 31534487 = 31534834
491 + 31534343 = 31534834
563 + 31534271 = 31534834

Showing the first eight; more decompositions exist.
