Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 957820, here are decompositions:

47 + 957773 = 957820
89 + 957731 = 957820
179 + 957641 = 957820
233 + 957587 = 957820
257 + 957563 = 957820
263 + 957557 = 957820
389 + 957431 = 957820
401 + 957419 = 957820

Showing the first eight; more decompositions exist.
