Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492622, here are decompositions:

19 + 31492603 = 31492622
151 + 31492471 = 31492622
193 + 31492429 = 31492622
199 + 31492423 = 31492622
223 + 31492399 = 31492622
229 + 31492393 = 31492622
379 + 31492243 = 31492622
409 + 31492213 = 31492622

Showing the first eight; more decompositions exist.
