Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939580, here are decompositions:

29 + 939551 = 939580
137 + 939443 = 939580
149 + 939431 = 939580
167 + 939413 = 939580
233 + 939347 = 939580
263 + 939317 = 939580
281 + 939299 = 939580
293 + 939287 = 939580

Showing the first eight; more decompositions exist.
