Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585092, here are decompositions:

13 + 31585079 = 31585092
31 + 31585061 = 31585092
59 + 31585033 = 31585092
73 + 31585019 = 31585092
131 + 31584961 = 31585092
139 + 31584953 = 31585092
191 + 31584901 = 31585092
211 + 31584881 = 31585092

Showing the first eight; more decompositions exist.
