Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466604, here are decompositions:

7 + 31466597 = 31466604
17 + 31466587 = 31466604
41 + 31466563 = 31466604
101 + 31466503 = 31466604
223 + 31466381 = 31466604
263 + 31466341 = 31466604
277 + 31466327 = 31466604
313 + 31466291 = 31466604

Showing the first eight; more decompositions exist.
