Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172942, here are decompositions:

59 + 172883 = 172942
71 + 172871 = 172942
83 + 172859 = 172942
89 + 172853 = 172942
113 + 172829 = 172942
191 + 172751 = 172942
233 + 172709 = 172942
269 + 172673 = 172942

Showing the first eight; more decompositions exist.
