Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188444, here are decompositions:

7 + 188437 = 188444
13 + 188431 = 188444
37 + 188407 = 188444
43 + 188401 = 188444
127 + 188317 = 188444
163 + 188281 = 188444
307 + 188137 = 188444
337 + 188107 = 188444

Showing the first eight; more decompositions exist.
