Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463368, here are decompositions:

5 + 31463363 = 31463368
47 + 31463321 = 31463368
107 + 31463261 = 31463368
269 + 31463099 = 31463368
281 + 31463087 = 31463368
389 + 31462979 = 31463368
467 + 31462901 = 31463368
479 + 31462889 = 31463368

Showing the first eight; more decompositions exist.
