Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173898, here are decompositions:

7 + 173891 = 173898
31 + 173867 = 173898
37 + 173861 = 173898
47 + 173851 = 173898
59 + 173839 = 173898
71 + 173827 = 173898
79 + 173819 = 173898
157 + 173741 = 173898

Showing the first eight; more decompositions exist.
