Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463446, here are decompositions:

17 + 31463429 = 31463446
59 + 31463387 = 31463446
83 + 31463363 = 31463446
197 + 31463249 = 31463446
233 + 31463213 = 31463446
347 + 31463099 = 31463446
359 + 31463087 = 31463446
383 + 31463063 = 31463446

Showing the first eight; more decompositions exist.
