Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471594, here are decompositions:

3 + 31471591 = 31471594
17 + 31471577 = 31471594
71 + 31471523 = 31471594
83 + 31471511 = 31471594
113 + 31471481 = 31471594
137 + 31471457 = 31471594
197 + 31471397 = 31471594
233 + 31471361 = 31471594

Showing the first eight; more decompositions exist.
