Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187254, here are decompositions:

17 + 187237 = 187254
31 + 187223 = 187254
37 + 187217 = 187254
43 + 187211 = 187254
61 + 187193 = 187254
73 + 187181 = 187254
83 + 187171 = 187254
113 + 187141 = 187254

Showing the first eight; more decompositions exist.
