Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160420, here are decompositions:

11 + 160409 = 160420
17 + 160403 = 160420
23 + 160397 = 160420
47 + 160373 = 160420
53 + 160367 = 160420
101 + 160319 = 160420
107 + 160313 = 160420
167 + 160253 = 160420

Showing the first eight; more decompositions exist.
