Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045392, here are decompositions:

43 + 1045349 = 1045392
71 + 1045321 = 1045392
83 + 1045309 = 1045392
151 + 1045241 = 1045392
163 + 1045229 = 1045392
193 + 1045199 = 1045392
199 + 1045193 = 1045392
239 + 1045153 = 1045392

Showing the first eight; more decompositions exist.
