Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466000, here are decompositions:

109 + 31465891 = 31466000
151 + 31465849 = 31466000
199 + 31465801 = 31466000
211 + 31465789 = 31466000
337 + 31465663 = 31466000
421 + 31465579 = 31466000
439 + 31465561 = 31466000
541 + 31465459 = 31466000

Showing the first eight; more decompositions exist.
