Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187992, here are decompositions:

5 + 187987 = 187992
19 + 187973 = 187992
29 + 187963 = 187992
41 + 187951 = 187992
61 + 187931 = 187992
71 + 187921 = 187992
83 + 187909 = 187992
109 + 187883 = 187992

Showing the first eight; more decompositions exist.
