Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466026, here are decompositions:

23 + 31466003 = 31466026
47 + 31465979 = 31466026
197 + 31465829 = 31466026
269 + 31465757 = 31466026
353 + 31465673 = 31466026
479 + 31465547 = 31466026
1217 + 31464809 = 31466026
1409 + 31464617 = 31466026

Showing the first eight; more decompositions exist.
