Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477702, here are decompositions:

5 + 31477697 = 31477702
131 + 31477571 = 31477702
149 + 31477553 = 31477702
353 + 31477349 = 31477702
401 + 31477301 = 31477702
521 + 31477181 = 31477702
743 + 31476959 = 31477702
821 + 31476881 = 31477702

Showing the first eight; more decompositions exist.
