Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67648, here are decompositions:

17 + 67631 = 67648
29 + 67619 = 67648
41 + 67607 = 67648
47 + 67601 = 67648
59 + 67589 = 67648
71 + 67577 = 67648
89 + 67559 = 67648
101 + 67547 = 67648

Showing the first eight; more decompositions exist.
