Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187632, here are decompositions:

59 + 187573 = 187632
73 + 187559 = 187632
101 + 187531 = 187632
163 + 187469 = 187632
191 + 187441 = 187632
199 + 187433 = 187632
223 + 187409 = 187632
239 + 187393 = 187632

Showing the first eight; more decompositions exist.
