Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188436, here are decompositions:

5 + 188431 = 188436
19 + 188417 = 188436
29 + 188407 = 188436
47 + 188389 = 188436
67 + 188369 = 188436
103 + 188333 = 188436
113 + 188323 = 188436
137 + 188299 = 188436

Showing the first eight; more decompositions exist.
