Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67810, here are decompositions:

3 + 67807 = 67810
47 + 67763 = 67810
53 + 67757 = 67810
59 + 67751 = 67810
101 + 67709 = 67810
131 + 67679 = 67810
179 + 67631 = 67810
191 + 67619 = 67810

Showing the first eight; more decompositions exist.
