Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453476, here are decompositions:

13 + 31453463 = 31453476
29 + 31453447 = 31453476
83 + 31453393 = 31453476
193 + 31453283 = 31453476
227 + 31453249 = 31453476
269 + 31453207 = 31453476
283 + 31453193 = 31453476
317 + 31453159 = 31453476

Showing the first eight; more decompositions exist.
