Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173992, here are decompositions:

11 + 173981 = 173992
23 + 173969 = 173992
59 + 173933 = 173992
83 + 173909 = 173992
101 + 173891 = 173992
131 + 173861 = 173992
173 + 173819 = 173992
251 + 173741 = 173992

Showing the first eight; more decompositions exist.
