Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173072, here are decompositions:

13 + 173059 = 173072
19 + 173053 = 173072
73 + 172999 = 173072
79 + 172993 = 173072
103 + 172969 = 173072
139 + 172933 = 173072
223 + 172849 = 173072
271 + 172801 = 173072

Showing the first eight; more decompositions exist.
