Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463782, here are decompositions:

3 + 31463779 = 31463782
23 + 31463759 = 31463782
101 + 31463681 = 31463782
191 + 31463591 = 31463782
263 + 31463519 = 31463782
293 + 31463489 = 31463782
353 + 31463429 = 31463782
419 + 31463363 = 31463782

Showing the first eight; more decompositions exist.
