Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541718, here are decompositions:

11 + 31541707 = 31541718
41 + 31541677 = 31541718
59 + 31541659 = 31541718
67 + 31541651 = 31541718
107 + 31541611 = 31541718
127 + 31541591 = 31541718
137 + 31541581 = 31541718
149 + 31541569 = 31541718

Showing the first eight; more decompositions exist.
