Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187282, here are decompositions:

5 + 187277 = 187282
59 + 187223 = 187282
71 + 187211 = 187282
89 + 187193 = 187282
101 + 187181 = 187282
149 + 187133 = 187282
191 + 187091 = 187282
233 + 187049 = 187282

Showing the first eight; more decompositions exist.
