Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981012, here are decompositions:

13 + 980999 = 981012
101 + 980911 = 981012
103 + 980909 = 981012
113 + 980899 = 981012
181 + 980831 = 981012
211 + 980801 = 981012
239 + 980773 = 981012
281 + 980731 = 981012

Showing the first eight; more decompositions exist.
