Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986478, here are decompositions:

7 + 986471 = 986478
41 + 986437 = 986478
61 + 986417 = 986478
67 + 986411 = 986478
109 + 986369 = 986478
127 + 986351 = 986478
139 + 986339 = 986478
191 + 986287 = 986478

Showing the first eight; more decompositions exist.
