Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187452, here are decompositions:

11 + 187441 = 187452
19 + 187433 = 187452
29 + 187423 = 187452
43 + 187409 = 187452
59 + 187393 = 187452
73 + 187379 = 187452
79 + 187373 = 187452
103 + 187349 = 187452

Showing the first eight; more decompositions exist.
