Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188402, here are decompositions:

13 + 188389 = 188402
43 + 188359 = 188402
79 + 188323 = 188402
103 + 188299 = 188402
223 + 188179 = 188402
373 + 188029 = 188402
439 + 187963 = 188402
541 + 187861 = 188402

Showing the first eight; more decompositions exist.
