Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67720, here are decompositions:

11 + 67709 = 67720
41 + 67679 = 67720
89 + 67631 = 67720
101 + 67619 = 67720
113 + 67607 = 67720
131 + 67589 = 67720
173 + 67547 = 67720
197 + 67523 = 67720

Showing the first eight; more decompositions exist.
