Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015190, here are decompositions:

19 + 1015171 = 1015190
31 + 1015159 = 1015190
67 + 1015123 = 1015190
97 + 1015093 = 1015190
109 + 1015081 = 1015190
139 + 1015051 = 1015190
151 + 1015039 = 1015190
181 + 1015009 = 1015190

Showing the first eight; more decompositions exist.
