Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470676, here are decompositions:

23 + 31470653 = 31470676
47 + 31470629 = 31470676
53 + 31470623 = 31470676
113 + 31470563 = 31470676
233 + 31470443 = 31470676
317 + 31470359 = 31470676
353 + 31470323 = 31470676
383 + 31470293 = 31470676

Showing the first eight; more decompositions exist.
