Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461898, here are decompositions:

5 + 31461893 = 31461898
11 + 31461887 = 31461898
47 + 31461851 = 31461898
107 + 31461791 = 31461898
137 + 31461761 = 31461898
257 + 31461641 = 31461898
557 + 31461341 = 31461898
617 + 31461281 = 31461898

Showing the first eight; more decompositions exist.
