Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167888, here are decompositions:

79 + 167809 = 167888
109 + 167779 = 167888
211 + 167677 = 167888
277 + 167611 = 167888
367 + 167521 = 167888
397 + 167491 = 167888
439 + 167449 = 167888
547 + 167341 = 167888

Showing the first eight; more decompositions exist.
