Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981736, here are decompositions:

5 + 981731 = 981736
23 + 981713 = 981736
29 + 981707 = 981736
53 + 981683 = 981736
83 + 981653 = 981736
113 + 981623 = 981736
137 + 981599 = 981736
149 + 981587 = 981736

Showing the first eight; more decompositions exist.
