Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172736, here are decompositions:

19 + 172717 = 172736
73 + 172663 = 172736
79 + 172657 = 172736
103 + 172633 = 172736
139 + 172597 = 172736
163 + 172573 = 172736
229 + 172507 = 172736
313 + 172423 = 172736

Showing the first eight; more decompositions exist.
