Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468876, here are decompositions:

53 + 31468823 = 31468876
83 + 31468793 = 31468876
149 + 31468727 = 31468876
239 + 31468637 = 31468876
317 + 31468559 = 31468876
347 + 31468529 = 31468876
353 + 31468523 = 31468876
359 + 31468517 = 31468876

Showing the first eight; more decompositions exist.
