Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980786, here are decompositions:

13 + 980773 = 980786
67 + 980719 = 980786
97 + 980689 = 980786
109 + 980677 = 980786
193 + 980593 = 980786
199 + 980587 = 980786
229 + 980557 = 980786
283 + 980503 = 980786

Showing the first eight; more decompositions exist.
