Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181752, here are decompositions:

13 + 181739 = 181752
23 + 181729 = 181752
31 + 181721 = 181752
41 + 181711 = 181752
59 + 181693 = 181752
83 + 181669 = 181752
113 + 181639 = 181752
149 + 181603 = 181752

Showing the first eight; more decompositions exist.
