Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939472, here are decompositions:

3 + 939469 = 939472
29 + 939443 = 939472
41 + 939431 = 939472
59 + 939413 = 939472
113 + 939359 = 939472
173 + 939299 = 939472
179 + 939293 = 939472
269 + 939203 = 939472

Showing the first eight; more decompositions exist.
