Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980420, here are decompositions:

3 + 980417 = 980420
19 + 980401 = 980420
43 + 980377 = 980420
127 + 980293 = 980420
223 + 980197 = 980420
241 + 980179 = 980420
271 + 980149 = 980420
283 + 980137 = 980420

Showing the first eight; more decompositions exist.
