Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027686, here are decompositions:

7 + 1027679 = 1027686
43 + 1027643 = 1027686
73 + 1027613 = 1027686
89 + 1027597 = 1027686
137 + 1027549 = 1027686
139 + 1027547 = 1027686
167 + 1027519 = 1027686
193 + 1027493 = 1027686

Showing the first eight; more decompositions exist.
