Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535292, here are decompositions:

29 + 31535263 = 31535292
59 + 31535233 = 31535292
73 + 31535219 = 31535292
79 + 31535213 = 31535292
109 + 31535183 = 31535292
149 + 31535143 = 31535292
179 + 31535113 = 31535292
211 + 31535081 = 31535292

Showing the first eight; more decompositions exist.
