Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477306, here are decompositions:

5 + 31477301 = 31477306
17 + 31477289 = 31477306
227 + 31477079 = 31477306
239 + 31477067 = 31477306
347 + 31476959 = 31477306
359 + 31476947 = 31477306
389 + 31476917 = 31477306
563 + 31476743 = 31477306

Showing the first eight; more decompositions exist.
