Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187482, here are decompositions:

5 + 187477 = 187482
11 + 187471 = 187482
13 + 187469 = 187482
19 + 187463 = 187482
41 + 187441 = 187482
59 + 187423 = 187482
73 + 187409 = 187482
89 + 187393 = 187482

Showing the first eight; more decompositions exist.
