Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176538, here are decompositions:

7 + 176531 = 176538
17 + 176521 = 176538
29 + 176509 = 176538
31 + 176507 = 176538
41 + 176497 = 176538
71 + 176467 = 176538
79 + 176459 = 176538
107 + 176431 = 176538

Showing the first eight; more decompositions exist.
