Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478092, here are decompositions:

3 + 31478089 = 31478092
11 + 31478081 = 31478092
101 + 31477991 = 31478092
251 + 31477841 = 31478092
281 + 31477811 = 31478092
293 + 31477799 = 31478092
311 + 31477781 = 31478092
509 + 31477583 = 31478092

Showing the first eight; more decompositions exist.
