Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477112, here are decompositions:

13 + 31477099 = 31477112
61 + 31477051 = 31477112
181 + 31476931 = 31477112
241 + 31476871 = 31477112
283 + 31476829 = 31477112
313 + 31476799 = 31477112
379 + 31476733 = 31477112
409 + 31476703 = 31477112

Showing the first eight; more decompositions exist.
