Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980906, here are decompositions:

7 + 980899 = 980906
13 + 980893 = 980906
19 + 980887 = 980906
79 + 980827 = 980906
103 + 980803 = 980906
229 + 980677 = 980906
307 + 980599 = 980906
313 + 980593 = 980906

Showing the first eight; more decompositions exist.
