Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466198, here are decompositions:

61 + 31466137 = 31466198
79 + 31466119 = 31466198
97 + 31466101 = 31466198
109 + 31466089 = 31466198
199 + 31465999 = 31466198
307 + 31465891 = 31466198
349 + 31465849 = 31466198
367 + 31465831 = 31466198

Showing the first eight; more decompositions exist.
