Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188532, here are decompositions:

5 + 188527 = 188532
13 + 188519 = 188532
41 + 188491 = 188532
59 + 188473 = 188532
73 + 188459 = 188532
89 + 188443 = 188532
101 + 188431 = 188532
131 + 188401 = 188532

Showing the first eight; more decompositions exist.
