Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585062, here are decompositions:

29 + 31585033 = 31585062
43 + 31585019 = 31585062
101 + 31584961 = 31585062
109 + 31584953 = 31585062
181 + 31584881 = 31585062
193 + 31584869 = 31585062
233 + 31584829 = 31585062
239 + 31584823 = 31585062

Showing the first eight; more decompositions exist.
