Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541696, here are decompositions:

3 + 31541693 = 31541696
19 + 31541677 = 31541696
37 + 31541659 = 31541696
127 + 31541569 = 31541696
139 + 31541557 = 31541696
229 + 31541467 = 31541696
337 + 31541359 = 31541696
349 + 31541347 = 31541696

Showing the first eight; more decompositions exist.
