Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020340, here are decompositions:

3 + 1020337 = 1020340
11 + 1020329 = 1020340
47 + 1020293 = 1020340
71 + 1020269 = 1020340
107 + 1020233 = 1020340
197 + 1020143 = 1020340
227 + 1020113 = 1020340
239 + 1020101 = 1020340

Showing the first eight; more decompositions exist.
