Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543476, here are decompositions:

23 + 31543453 = 31543476
47 + 31543429 = 31543476
79 + 31543397 = 31543476
127 + 31543349 = 31543476
233 + 31543243 = 31543476
257 + 31543219 = 31543476
269 + 31543207 = 31543476
313 + 31543163 = 31543476

Showing the first eight; more decompositions exist.
