Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188588, here are decompositions:

61 + 188527 = 188588
97 + 188491 = 188588
151 + 188437 = 188588
157 + 188431 = 188588
181 + 188407 = 188588
199 + 188389 = 188588
229 + 188359 = 188588
271 + 188317 = 188588

Showing the first eight; more decompositions exist.
