Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468936, here are decompositions:

17 + 31468919 = 31468936
113 + 31468823 = 31468936
179 + 31468757 = 31468936
269 + 31468667 = 31468936
347 + 31468589 = 31468936
383 + 31468553 = 31468936
419 + 31468517 = 31468936
599 + 31468337 = 31468936

Showing the first eight; more decompositions exist.
