Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468698, here are decompositions:

31 + 31468667 = 31468698
61 + 31468637 = 31468698
67 + 31468631 = 31468698
101 + 31468597 = 31468698
109 + 31468589 = 31468698
127 + 31468571 = 31468698
139 + 31468559 = 31468698
181 + 31468517 = 31468698

Showing the first eight; more decompositions exist.
