Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492934, here are decompositions:

13 + 31492921 = 31492934
97 + 31492837 = 31492934
157 + 31492777 = 31492934
163 + 31492771 = 31492934
271 + 31492663 = 31492934
283 + 31492651 = 31492934
307 + 31492627 = 31492934
331 + 31492603 = 31492934

Showing the first eight; more decompositions exist.
