Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015028, here are decompositions:

19 + 1015009 = 1015028
139 + 1014889 = 1015028
151 + 1014877 = 1015028
211 + 1014817 = 1015028
241 + 1014787 = 1015028
307 + 1014721 = 1015028
331 + 1014697 = 1015028
379 + 1014649 = 1015028

Showing the first eight; more decompositions exist.
