Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466954, here are decompositions:

3 + 31466951 = 31466954
61 + 31466893 = 31466954
97 + 31466857 = 31466954
163 + 31466791 = 31466954
223 + 31466731 = 31466954
241 + 31466713 = 31466954
283 + 31466671 = 31466954
367 + 31466587 = 31466954

Showing the first eight; more decompositions exist.
