Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68842, here are decompositions:

23 + 68819 = 68842
29 + 68813 = 68842
71 + 68771 = 68842
113 + 68729 = 68842
131 + 68711 = 68842
173 + 68669 = 68842
311 + 68531 = 68842
353 + 68489 = 68842

Showing the first eight; more decompositions exist.
