Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189446, here are decompositions:

7 + 189439 = 189446
13 + 189433 = 189446
97 + 189349 = 189446
109 + 189337 = 189446
139 + 189307 = 189446
193 + 189253 = 189446
223 + 189223 = 189446
277 + 189169 = 189446

Showing the first eight; more decompositions exist.
