Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492446, here are decompositions:

17 + 31492429 = 31492446
23 + 31492423 = 31492446
43 + 31492403 = 31492446
47 + 31492399 = 31492446
53 + 31492393 = 31492446
109 + 31492337 = 31492446
127 + 31492319 = 31492446
233 + 31492213 = 31492446

Showing the first eight; more decompositions exist.
