Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980090, here are decompositions:

19 + 980071 = 980090
43 + 980047 = 980090
103 + 979987 = 980090
271 + 979819 = 980090
283 + 979807 = 980090
373 + 979717 = 980090
439 + 979651 = 980090
523 + 979567 = 980090

Showing the first eight; more decompositions exist.
