Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015392, here are decompositions:

23 + 1015369 = 1015392
29 + 1015363 = 1015392
31 + 1015361 = 1015392
43 + 1015349 = 1015392
83 + 1015309 = 1015392
193 + 1015199 = 1015392
229 + 1015163 = 1015392
233 + 1015159 = 1015392

Showing the first eight; more decompositions exist.
