Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187418, here are decompositions:

31 + 187387 = 187418
79 + 187339 = 187418
181 + 187237 = 187418
199 + 187219 = 187418
229 + 187189 = 187418
241 + 187177 = 187418
277 + 187141 = 187418
307 + 187111 = 187418

Showing the first eight; more decompositions exist.
