Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981738, here are decompositions:

7 + 981731 = 981738
31 + 981707 = 981738
41 + 981697 = 981738
47 + 981691 = 981738
101 + 981637 = 981738
137 + 981601 = 981738
139 + 981599 = 981738
151 + 981587 = 981738

Showing the first eight; more decompositions exist.
