Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499354, here are decompositions:

13 + 31499341 = 31499354
31 + 31499323 = 31499354
43 + 31499311 = 31499354
127 + 31499227 = 31499354
193 + 31499161 = 31499354
277 + 31499077 = 31499354
331 + 31499023 = 31499354
457 + 31498897 = 31499354

Showing the first eight; more decompositions exist.
