Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585526, here are decompositions:

67 + 31585459 = 31585526
73 + 31585453 = 31585526
79 + 31585447 = 31585526
127 + 31585399 = 31585526
157 + 31585369 = 31585526
199 + 31585327 = 31585526
337 + 31585189 = 31585526
367 + 31585159 = 31585526

Showing the first eight; more decompositions exist.
