Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462894, here are decompositions:

5 + 31462889 = 31462894
17 + 31462877 = 31462894
83 + 31462811 = 31462894
101 + 31462793 = 31462894
137 + 31462757 = 31462894
311 + 31462583 = 31462894
317 + 31462577 = 31462894
347 + 31462547 = 31462894

Showing the first eight; more decompositions exist.
