Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028472, here are decompositions:

61 + 1028411 = 1028472
79 + 1028393 = 1028472
83 + 1028389 = 1028472
139 + 1028333 = 1028472
163 + 1028309 = 1028472
199 + 1028273 = 1028472
229 + 1028243 = 1028472
241 + 1028231 = 1028472

Showing the first eight; more decompositions exist.
