Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172526, here are decompositions:

7 + 172519 = 172526
19 + 172507 = 172526
37 + 172489 = 172526
103 + 172423 = 172526
127 + 172399 = 172526
229 + 172297 = 172526
283 + 172243 = 172526
307 + 172219 = 172526

Showing the first eight; more decompositions exist.
