Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160722, here are decompositions:

11 + 160711 = 160722
13 + 160709 = 160722
41 + 160681 = 160722
53 + 160669 = 160722
59 + 160663 = 160722
71 + 160651 = 160722
73 + 160649 = 160722
83 + 160639 = 160722

Showing the first eight; more decompositions exist.
