Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117820, here are decompositions:

11 + 117809 = 117820
23 + 117797 = 117820
41 + 117779 = 117820
47 + 117773 = 117820
89 + 117731 = 117820
149 + 117671 = 117820
257 + 117563 = 117820
281 + 117539 = 117820

Showing the first eight; more decompositions exist.
