Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056542, here are decompositions:

61 + 1056481 = 1056542
73 + 1056469 = 1056542
79 + 1056463 = 1056542
163 + 1056379 = 1056542
181 + 1056361 = 1056542
271 + 1056271 = 1056542
373 + 1056169 = 1056542
433 + 1056109 = 1056542

Showing the first eight; more decompositions exist.
