Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477070, here are decompositions:

3 + 31477067 = 31477070
7 + 31477063 = 31477070
13 + 31477057 = 31477070
19 + 31477051 = 31477070
43 + 31477027 = 31477070
139 + 31476931 = 31477070
199 + 31476871 = 31477070
223 + 31476847 = 31477070

Showing the first eight; more decompositions exist.
