Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541678, here are decompositions:

19 + 31541659 = 31541678
67 + 31541611 = 31541678
97 + 31541581 = 31541678
109 + 31541569 = 31541678
151 + 31541527 = 31541678
211 + 31541467 = 31541678
229 + 31541449 = 31541678
241 + 31541437 = 31541678

Showing the first eight; more decompositions exist.
