Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461678, here are decompositions:

5 + 31461673 = 31461678
37 + 31461641 = 31461678
107 + 31461571 = 31461678
109 + 31461569 = 31461678
191 + 31461487 = 31461678
197 + 31461481 = 31461678
251 + 31461427 = 31461678
317 + 31461361 = 31461678

Showing the first eight; more decompositions exist.
