Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482986, here are decompositions:

13 + 31482973 = 31482986
79 + 31482907 = 31482986
97 + 31482889 = 31482986
127 + 31482859 = 31482986
163 + 31482823 = 31482986
277 + 31482709 = 31482986
373 + 31482613 = 31482986
487 + 31482499 = 31482986

Showing the first eight; more decompositions exist.
