Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188446, here are decompositions:

3 + 188443 = 188446
29 + 188417 = 188446
113 + 188333 = 188446
173 + 188273 = 188446
197 + 188249 = 188446
257 + 188189 = 188446
563 + 187883 = 188446
569 + 187877 = 188446

Showing the first eight; more decompositions exist.
