Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187792, here are decompositions:

5 + 187787 = 187792
29 + 187763 = 187792
41 + 187751 = 187792
71 + 187721 = 187792
131 + 187661 = 187792
233 + 187559 = 187792
359 + 187433 = 187792
383 + 187409 = 187792

Showing the first eight; more decompositions exist.
