Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980406, here are decompositions:

5 + 980401 = 980406
13 + 980393 = 980406
29 + 980377 = 980406
43 + 980363 = 980406
79 + 980327 = 980406
107 + 980299 = 980406
113 + 980293 = 980406
157 + 980249 = 980406

Showing the first eight; more decompositions exist.
