Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160578, here are decompositions:

37 + 160541 = 160578
71 + 160507 = 160578
79 + 160499 = 160578
97 + 160481 = 160578
137 + 160441 = 160578
181 + 160397 = 160578
191 + 160387 = 160578
211 + 160367 = 160578

Showing the first eight; more decompositions exist.
