Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468972, here are decompositions:

5 + 31468967 = 31468972
53 + 31468919 = 31468972
71 + 31468901 = 31468972
149 + 31468823 = 31468972
179 + 31468793 = 31468972
383 + 31468589 = 31468972
401 + 31468571 = 31468972
419 + 31468553 = 31468972

Showing the first eight; more decompositions exist.
