Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461994, here are decompositions:

17 + 31461977 = 31461994
71 + 31461923 = 31461994
101 + 31461893 = 31461994
107 + 31461887 = 31461994
233 + 31461761 = 31461994
251 + 31461743 = 31461994
257 + 31461737 = 31461994
353 + 31461641 = 31461994

Showing the first eight; more decompositions exist.
