Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532292, here are decompositions:

13 + 31532279 = 31532292
23 + 31532269 = 31532292
31 + 31532261 = 31532292
73 + 31532219 = 31532292
83 + 31532209 = 31532292
89 + 31532203 = 31532292
151 + 31532141 = 31532292
179 + 31532113 = 31532292

Showing the first eight; more decompositions exist.
