Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585476, here are decompositions:

7 + 31585469 = 31585476
17 + 31585459 = 31585476
23 + 31585453 = 31585476
29 + 31585447 = 31585476
107 + 31585369 = 31585476
137 + 31585339 = 31585476
149 + 31585327 = 31585476
157 + 31585319 = 31585476

Showing the first eight; more decompositions exist.
