Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541708, here are decompositions:

31 + 31541677 = 31541708
97 + 31541611 = 31541708
127 + 31541581 = 31541708
139 + 31541569 = 31541708
151 + 31541557 = 31541708
181 + 31541527 = 31541708
199 + 31541509 = 31541708
241 + 31541467 = 31541708

Showing the first eight; more decompositions exist.
