Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027742, here are decompositions:

3 + 1027739 = 1027742
151 + 1027591 = 1027742
193 + 1027549 = 1027742
223 + 1027519 = 1027742
271 + 1027471 = 1027742
283 + 1027459 = 1027742
421 + 1027321 = 1027742
613 + 1027129 = 1027742

Showing the first eight; more decompositions exist.
