Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466810, here are decompositions:

19 + 31466791 = 31466810
61 + 31466749 = 31466810
79 + 31466731 = 31466810
97 + 31466713 = 31466810
103 + 31466707 = 31466810
139 + 31466671 = 31466810
181 + 31466629 = 31466810
223 + 31466587 = 31466810

Showing the first eight; more decompositions exist.
