Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466768, here are decompositions:

19 + 31466749 = 31466768
37 + 31466731 = 31466768
61 + 31466707 = 31466768
79 + 31466689 = 31466768
97 + 31466671 = 31466768
139 + 31466629 = 31466768
181 + 31466587 = 31466768
367 + 31466401 = 31466768

Showing the first eight; more decompositions exist.
