Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463404, here are decompositions:

17 + 31463387 = 31463404
41 + 31463363 = 31463404
83 + 31463321 = 31463404
191 + 31463213 = 31463404
257 + 31463147 = 31463404
281 + 31463123 = 31463404
317 + 31463087 = 31463404
503 + 31462901 = 31463404

Showing the first eight; more decompositions exist.
