Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478062, here are decompositions:

71 + 31477991 = 31478062
179 + 31477883 = 31478062
191 + 31477871 = 31478062
251 + 31477811 = 31478062
263 + 31477799 = 31478062
269 + 31477793 = 31478062
281 + 31477781 = 31478062
311 + 31477751 = 31478062

Showing the first eight; more decompositions exist.
