Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981774, here are decompositions:

5 + 981769 = 981774
43 + 981731 = 981774
61 + 981713 = 981774
67 + 981707 = 981774
71 + 981703 = 981774
83 + 981691 = 981774
137 + 981637 = 981774
151 + 981623 = 981774

Showing the first eight; more decompositions exist.
