Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187708, here are decompositions:

47 + 187661 = 187708
71 + 187637 = 187708
149 + 187559 = 187708
239 + 187469 = 187708
347 + 187361 = 187708
359 + 187349 = 187708
431 + 187277 = 187708
491 + 187217 = 187708

Showing the first eight; more decompositions exist.
