Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040320, here are decompositions:

101 + 1040219 = 1040320
131 + 1040189 = 1040320
137 + 1040183 = 1040320
167 + 1040153 = 1040320
179 + 1040141 = 1040320
227 + 1040093 = 1040320
251 + 1040069 = 1040320
263 + 1040057 = 1040320

Showing the first eight; more decompositions exist.
