Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585598, here are decompositions:

19 + 31585579 = 31585598
61 + 31585537 = 31585598
97 + 31585501 = 31585598
139 + 31585459 = 31585598
151 + 31585447 = 31585598
157 + 31585441 = 31585598
199 + 31585399 = 31585598
229 + 31585369 = 31585598

Showing the first eight; more decompositions exist.
