Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981038, here are decompositions:

127 + 980911 = 981038
139 + 980899 = 981038
151 + 980887 = 981038
211 + 980827 = 981038
307 + 980731 = 981038
349 + 980689 = 981038
397 + 980641 = 981038
439 + 980599 = 981038

Showing the first eight; more decompositions exist.
