Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81068, here are decompositions:

19 + 81049 = 81068
37 + 81031 = 81068
67 + 81001 = 81068
79 + 80989 = 81068
139 + 80929 = 81068
151 + 80917 = 81068
157 + 80911 = 81068
307 + 80761 = 81068

Showing the first eight; more decompositions exist.
