Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189220, here are decompositions:

71 + 189149 = 189220
179 + 189041 = 189220
263 + 188957 = 189220
281 + 188939 = 189220
293 + 188927 = 189220
359 + 188861 = 189220
389 + 188831 = 189220
419 + 188801 = 189220

Showing the first eight; more decompositions exist.
