Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021622, here are decompositions:

61 + 1021561 = 1021622
139 + 1021483 = 1021622
181 + 1021441 = 1021622
193 + 1021429 = 1021622
241 + 1021381 = 1021622
331 + 1021291 = 1021622
379 + 1021243 = 1021622
439 + 1021183 = 1021622

Showing the first eight; more decompositions exist.
