Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462198, here are decompositions:

71 + 31462127 = 31462198
191 + 31462007 = 31462198
311 + 31461887 = 31462198
347 + 31461851 = 31462198
419 + 31461779 = 31462198
461 + 31461737 = 31462198
557 + 31461641 = 31462198
641 + 31461557 = 31462198

Showing the first eight; more decompositions exist.
