Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465582, here are decompositions:

3 + 31465579 = 31465582
11 + 31465571 = 31465582
53 + 31465529 = 31465582
101 + 31465481 = 31465582
131 + 31465451 = 31465582
191 + 31465391 = 31465582
293 + 31465289 = 31465582
359 + 31465223 = 31465582

Showing the first eight; more decompositions exist.
