Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541768, here are decompositions:

7 + 31541761 = 31541768
31 + 31541737 = 31541768
61 + 31541707 = 31541768
109 + 31541659 = 31541768
157 + 31541611 = 31541768
199 + 31541569 = 31541768
211 + 31541557 = 31541768
241 + 31541527 = 31541768

Showing the first eight; more decompositions exist.
