Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980388, here are decompositions:

11 + 980377 = 980388
61 + 980327 = 980388
67 + 980321 = 980388
89 + 980299 = 980388
127 + 980261 = 980388
139 + 980249 = 980388
191 + 980197 = 980388
229 + 980159 = 980388

Showing the first eight; more decompositions exist.
