Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477354, here are decompositions:

3 + 31477351 = 31477354
5 + 31477349 = 31477354
53 + 31477301 = 31477354
173 + 31477181 = 31477354
191 + 31477163 = 31477354
743 + 31476611 = 31477354
761 + 31476593 = 31477354
941 + 31476413 = 31477354

Showing the first eight; more decompositions exist.
