Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163580, here are decompositions:

7 + 163573 = 163580
13 + 163567 = 163580
19 + 163561 = 163580
37 + 163543 = 163580
97 + 163483 = 163580
103 + 163477 = 163580
163 + 163417 = 163580
229 + 163351 = 163580

Showing the first eight; more decompositions exist.
