Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106440, here are decompositions:

7 + 106433 = 106440
13 + 106427 = 106440
23 + 106417 = 106440
29 + 106411 = 106440
43 + 106397 = 106440
67 + 106373 = 106440
73 + 106367 = 106440
83 + 106357 = 106440

Showing the first eight; more decompositions exist.
