Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477292, here are decompositions:

3 + 31477289 = 31477292
79 + 31477213 = 31477292
151 + 31477141 = 31477292
181 + 31477111 = 31477292
193 + 31477099 = 31477292
229 + 31477063 = 31477292
241 + 31477051 = 31477292
271 + 31477021 = 31477292

Showing the first eight; more decompositions exist.
