Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470592, here are decompositions:

11 + 31470581 = 31470592
29 + 31470563 = 31470592
149 + 31470443 = 31470592
233 + 31470359 = 31470592
239 + 31470353 = 31470592
269 + 31470323 = 31470592
383 + 31470209 = 31470592
449 + 31470143 = 31470592

Showing the first eight; more decompositions exist.
