Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463380, here are decompositions:

17 + 31463363 = 31463380
59 + 31463321 = 31463380
131 + 31463249 = 31463380
167 + 31463213 = 31463380
233 + 31463147 = 31463380
257 + 31463123 = 31463380
281 + 31463099 = 31463380
293 + 31463087 = 31463380

Showing the first eight; more decompositions exist.
