Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477176, here are decompositions:

13 + 31477163 = 31477176
97 + 31477079 = 31477176
109 + 31477067 = 31477176
113 + 31477063 = 31477176
149 + 31477027 = 31477176
229 + 31476947 = 31477176
347 + 31476829 = 31477176
433 + 31476743 = 31477176

Showing the first eight; more decompositions exist.
