Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015402, here are decompositions:

41 + 1015361 = 1015402
53 + 1015349 = 1015402
239 + 1015163 = 1015402
263 + 1015139 = 1015402
359 + 1015043 = 1015402
449 + 1014953 = 1015402
461 + 1014941 = 1015402
569 + 1014833 = 1015402

Showing the first eight; more decompositions exist.
