Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585592, here are decompositions:

13 + 31585579 = 31585592
43 + 31585549 = 31585592
139 + 31585453 = 31585592
151 + 31585441 = 31585592
193 + 31585399 = 31585592
223 + 31585369 = 31585592
331 + 31585261 = 31585592
421 + 31585171 = 31585592

Showing the first eight; more decompositions exist.
