Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 957780, here are decompositions:

7 + 957773 = 957780
11 + 957769 = 957780
29 + 957751 = 957780
59 + 957721 = 957780
71 + 957709 = 957780
79 + 957701 = 957780
137 + 957643 = 957780
139 + 957641 = 957780

Showing the first eight; more decompositions exist.
