Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466582, here are decompositions:

19 + 31466563 = 31466582
79 + 31466503 = 31466582
181 + 31466401 = 31466582
193 + 31466389 = 31466582
241 + 31466341 = 31466582
331 + 31466251 = 31466582
349 + 31466233 = 31466582
409 + 31466173 = 31466582

Showing the first eight; more decompositions exist.
