Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477410, here are decompositions:

11 + 31477399 = 31477410
31 + 31477379 = 31477410
59 + 31477351 = 31477410
61 + 31477349 = 31477410
89 + 31477321 = 31477410
109 + 31477301 = 31477410
197 + 31477213 = 31477410
229 + 31477181 = 31477410

Showing the first eight; more decompositions exist.
