Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173918, here are decompositions:

67 + 173851 = 173918
79 + 173839 = 173918
139 + 173779 = 173918
211 + 173707 = 173918
271 + 173647 = 173918
379 + 173539 = 173918
421 + 173497 = 173918
487 + 173431 = 173918

Showing the first eight; more decompositions exist.
