Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67580, here are decompositions:

3 + 67577 = 67580
13 + 67567 = 67580
43 + 67537 = 67580
103 + 67477 = 67580
127 + 67453 = 67580
151 + 67429 = 67580
181 + 67399 = 67580
211 + 67369 = 67580

Showing the first eight; more decompositions exist.
