Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463416, here are decompositions:

29 + 31463387 = 31463416
53 + 31463363 = 31463416
167 + 31463249 = 31463416
269 + 31463147 = 31463416
293 + 31463123 = 31463416
317 + 31463099 = 31463416
353 + 31463063 = 31463416
659 + 31462757 = 31463416

Showing the first eight; more decompositions exist.
