Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67520, here are decompositions:

31 + 67489 = 67520
43 + 67477 = 67520
67 + 67453 = 67520
73 + 67447 = 67520
109 + 67411 = 67520
151 + 67369 = 67520
181 + 67339 = 67520
307 + 67213 = 67520

Showing the first eight; more decompositions exist.
