Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67530, here are decompositions:

7 + 67523 = 67530
19 + 67511 = 67530
31 + 67499 = 67530
37 + 67493 = 67530
41 + 67489 = 67530
53 + 67477 = 67530
83 + 67447 = 67530
97 + 67433 = 67530

Showing the first eight; more decompositions exist.
