Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027658, here are decompositions:

61 + 1027597 = 1027658
67 + 1027591 = 1027658
109 + 1027549 = 1027658
139 + 1027519 = 1027658
199 + 1027459 = 1027658
241 + 1027417 = 1027658
337 + 1027321 = 1027658
397 + 1027261 = 1027658

Showing the first eight; more decompositions exist.
