Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172758, here are decompositions:

7 + 172751 = 172758
17 + 172741 = 172758
37 + 172721 = 172758
41 + 172717 = 172758
71 + 172687 = 172758
101 + 172657 = 172758
109 + 172649 = 172758
139 + 172619 = 172758

Showing the first eight; more decompositions exist.
