Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945198, here are decompositions:

19 + 945179 = 945198
47 + 945151 = 945198
109 + 945089 = 945198
139 + 945059 = 945198
167 + 945031 = 945198
211 + 944987 = 945198
229 + 944969 = 945198
269 + 944929 = 945198

Showing the first eight; more decompositions exist.
