Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173850, here are decompositions:

11 + 173839 = 173850
23 + 173827 = 173850
31 + 173819 = 173850
43 + 173807 = 173850
67 + 173783 = 173850
71 + 173779 = 173850
73 + 173777 = 173850
107 + 173743 = 173850

Showing the first eight; more decompositions exist.
