Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020194, here are decompositions:

31 + 1020163 = 1020194
37 + 1020157 = 1020194
151 + 1020043 = 1020194
157 + 1020037 = 1020194
181 + 1020013 = 1020194
193 + 1020001 = 1020194
223 + 1019971 = 1020194
337 + 1019857 = 1020194

Showing the first eight; more decompositions exist.
