Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188842, here are decompositions:

11 + 188831 = 188842
41 + 188801 = 188842
89 + 188753 = 188842
113 + 188729 = 188842
131 + 188711 = 188842
149 + 188693 = 188842
233 + 188609 = 188842
239 + 188603 = 188842

Showing the first eight; more decompositions exist.
