Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67918, here are decompositions:

17 + 67901 = 67918
89 + 67829 = 67918
167 + 67751 = 67918
239 + 67679 = 67918
311 + 67607 = 67918
317 + 67601 = 67918
359 + 67559 = 67918
419 + 67499 = 67918

Showing the first eight; more decompositions exist.
