Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463644, here are decompositions:

53 + 31463591 = 31463644
137 + 31463507 = 31463644
167 + 31463477 = 31463644
257 + 31463387 = 31463644
281 + 31463363 = 31463644
383 + 31463261 = 31463644
431 + 31463213 = 31463644
521 + 31463123 = 31463644

Showing the first eight; more decompositions exist.
