Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187692, here are decompositions:

5 + 187687 = 187692
23 + 187669 = 187692
31 + 187661 = 187692
41 + 187651 = 187692
53 + 187639 = 187692
59 + 187633 = 187692
61 + 187631 = 187692
179 + 187513 = 187692

Showing the first eight; more decompositions exist.
