Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173120, here are decompositions:

61 + 173059 = 173120
67 + 173053 = 173120
97 + 173023 = 173120
127 + 172993 = 173120
139 + 172981 = 173120
151 + 172969 = 173120
271 + 172849 = 173120
313 + 172807 = 173120

Showing the first eight; more decompositions exist.
