Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468732, here are decompositions:

5 + 31468727 = 31468732
101 + 31468631 = 31468732
173 + 31468559 = 31468732
179 + 31468553 = 31468732
233 + 31468499 = 31468732
401 + 31468331 = 31468732
443 + 31468289 = 31468732
461 + 31468271 = 31468732

Showing the first eight; more decompositions exist.
