Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463482, here are decompositions:

5 + 31463477 = 31463482
23 + 31463459 = 31463482
53 + 31463429 = 31463482
233 + 31463249 = 31463482
269 + 31463213 = 31463482
359 + 31463123 = 31463482
383 + 31463099 = 31463482
419 + 31463063 = 31463482

Showing the first eight; more decompositions exist.
