Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188276, here are decompositions:

3 + 188273 = 188276
79 + 188197 = 188276
97 + 188179 = 188276
139 + 188137 = 188276
313 + 187963 = 188276
349 + 187927 = 188276
367 + 187909 = 188276
379 + 187897 = 188276

Showing the first eight; more decompositions exist.
