Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159780, here are decompositions:

7 + 159773 = 159780
11 + 159769 = 159780
17 + 159763 = 159780
41 + 159739 = 159780
43 + 159737 = 159780
59 + 159721 = 159780
73 + 159707 = 159780
79 + 159701 = 159780

Showing the first eight; more decompositions exist.
