Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463434, here are decompositions:

5 + 31463429 = 31463434
47 + 31463387 = 31463434
71 + 31463363 = 31463434
113 + 31463321 = 31463434
173 + 31463261 = 31463434
311 + 31463123 = 31463434
347 + 31463087 = 31463434
503 + 31462931 = 31463434

Showing the first eight; more decompositions exist.
