Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187648, here are decompositions:

11 + 187637 = 187648
17 + 187631 = 187648
89 + 187559 = 187648
101 + 187547 = 187648
179 + 187469 = 187648
239 + 187409 = 187648
269 + 187379 = 187648
281 + 187367 = 187648

Showing the first eight; more decompositions exist.
