Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980990, here are decompositions:

79 + 980911 = 980990
97 + 980893 = 980990
103 + 980887 = 980990
139 + 980851 = 980990
163 + 980827 = 980990
271 + 980719 = 980990
313 + 980677 = 980990
349 + 980641 = 980990

Showing the first eight; more decompositions exist.
