Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463554, here are decompositions:

47 + 31463507 = 31463554
71 + 31463483 = 31463554
167 + 31463387 = 31463554
191 + 31463363 = 31463554
233 + 31463321 = 31463554
293 + 31463261 = 31463554
431 + 31463123 = 31463554
467 + 31463087 = 31463554

Showing the first eight; more decompositions exist.
