Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476854, here are decompositions:

7 + 31476847 = 31476854
127 + 31476727 = 31476854
151 + 31476703 = 31476854
163 + 31476691 = 31476854
223 + 31476631 = 31476854
307 + 31476547 = 31476854
337 + 31476517 = 31476854
397 + 31476457 = 31476854

Showing the first eight; more decompositions exist.
