Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027680, here are decompositions:

37 + 1027643 = 1027680
67 + 1027613 = 1027680
83 + 1027597 = 1027680
89 + 1027591 = 1027680
113 + 1027567 = 1027680
131 + 1027549 = 1027680
191 + 1027489 = 1027680
193 + 1027487 = 1027680

Showing the first eight; more decompositions exist.
