Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028360, here are decompositions:

31 + 1028329 = 1028360
43 + 1028317 = 1028360
97 + 1028263 = 1028360
139 + 1028221 = 1028360
211 + 1028149 = 1028360
271 + 1028089 = 1028360
313 + 1028047 = 1028360
331 + 1028029 = 1028360

Showing the first eight; more decompositions exist.
