Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559292, here are decompositions:

29 + 31559263 = 31559292
41 + 31559251 = 31559292
53 + 31559239 = 31559292
73 + 31559219 = 31559292
103 + 31559189 = 31559292
131 + 31559161 = 31559292
199 + 31559093 = 31559292
211 + 31559081 = 31559292

Showing the first eight; more decompositions exist.
