Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188992, here are decompositions:

53 + 188939 = 188992
59 + 188933 = 188992
101 + 188891 = 188992
131 + 188861 = 188992
149 + 188843 = 188992
191 + 188801 = 188992
239 + 188753 = 188992
263 + 188729 = 188992

Showing the first eight; more decompositions exist.
