Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466648, here are decompositions:

19 + 31466629 = 31466648
61 + 31466587 = 31466648
307 + 31466341 = 31466648
397 + 31466251 = 31466648
541 + 31466107 = 31466648
547 + 31466101 = 31466648
757 + 31465891 = 31466648
769 + 31465879 = 31466648

Showing the first eight; more decompositions exist.
