Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187798, here are decompositions:

5 + 187793 = 187798
11 + 187787 = 187798
47 + 187751 = 187798
137 + 187661 = 187798
167 + 187631 = 187798
239 + 187559 = 187798
251 + 187547 = 187798
389 + 187409 = 187798

Showing the first eight; more decompositions exist.
