Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172960, here are decompositions:

83 + 172877 = 172960
89 + 172871 = 172960
101 + 172859 = 172960
107 + 172853 = 172960
131 + 172829 = 172960
173 + 172787 = 172960
239 + 172721 = 172960
251 + 172709 = 172960

Showing the first eight; more decompositions exist.
