Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187612, here are decompositions:

53 + 187559 = 187612
149 + 187463 = 187612
179 + 187433 = 187612
233 + 187379 = 187612
239 + 187373 = 187612
251 + 187361 = 187612
263 + 187349 = 187612
389 + 187223 = 187612

Showing the first eight; more decompositions exist.
