Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67864, here are decompositions:

11 + 67853 = 67864
101 + 67763 = 67864
107 + 67757 = 67864
113 + 67751 = 67864
131 + 67733 = 67864
233 + 67631 = 67864
257 + 67607 = 67864
263 + 67601 = 67864

Showing the first eight; more decompositions exist.
