Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494198, here are decompositions:

19 + 31494179 = 31494198
37 + 31494161 = 31494198
41 + 31494157 = 31494198
79 + 31494119 = 31494198
101 + 31494097 = 31494198
107 + 31494091 = 31494198
157 + 31494041 = 31494198
199 + 31493999 = 31494198

Showing the first eight; more decompositions exist.
