Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172548, here are decompositions:

7 + 172541 = 172548
29 + 172519 = 172548
31 + 172517 = 172548
41 + 172507 = 172548
59 + 172489 = 172548
107 + 172441 = 172548
109 + 172439 = 172548
127 + 172421 = 172548

Showing the first eight; more decompositions exist.
