Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980428, here are decompositions:

5 + 980423 = 980428
11 + 980417 = 980428
101 + 980327 = 980428
107 + 980321 = 980428
167 + 980261 = 980428
179 + 980249 = 980428
269 + 980159 = 980428
311 + 980117 = 980428

Showing the first eight; more decompositions exist.
