Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056440, here are decompositions:

61 + 1056379 = 1056440
67 + 1056373 = 1056440
79 + 1056361 = 1056440
193 + 1056247 = 1056440
199 + 1056241 = 1056440
223 + 1056217 = 1056440
271 + 1056169 = 1056440
331 + 1056109 = 1056440

Showing the first eight; more decompositions exist.
