Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187756, here are decompositions:

5 + 187751 = 187756
197 + 187559 = 187756
293 + 187463 = 187756
347 + 187409 = 187756
383 + 187373 = 187756
389 + 187367 = 187756
419 + 187337 = 187756
479 + 187277 = 187756

Showing the first eight; more decompositions exist.
