Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187684, here are decompositions:

23 + 187661 = 187684
47 + 187637 = 187684
53 + 187631 = 187684
137 + 187547 = 187684
251 + 187433 = 187684
311 + 187373 = 187684
317 + 187367 = 187684
347 + 187337 = 187684

Showing the first eight; more decompositions exist.
