Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015398, here are decompositions:

29 + 1015369 = 1015398
31 + 1015367 = 1015398
37 + 1015361 = 1015398
89 + 1015309 = 1015398
191 + 1015207 = 1015398
199 + 1015199 = 1015398
227 + 1015171 = 1015398
239 + 1015159 = 1015398

Showing the first eight; more decompositions exist.
