Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167858, here are decompositions:

79 + 167779 = 167858
181 + 167677 = 167858
337 + 167521 = 167858
367 + 167491 = 167858
409 + 167449 = 167858
421 + 167437 = 167858
541 + 167317 = 167858
547 + 167311 = 167858

Showing the first eight; more decompositions exist.
