Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980408, here are decompositions:

7 + 980401 = 980408
31 + 980377 = 980408
109 + 980299 = 980408
211 + 980197 = 980408
229 + 980179 = 980408
271 + 980137 = 980408
277 + 980131 = 980408
337 + 980071 = 980408

Showing the first eight; more decompositions exist.
