Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455476, here are decompositions:

43 + 31455433 = 31455476
67 + 31455409 = 31455476
79 + 31455397 = 31455476
109 + 31455367 = 31455476
163 + 31455313 = 31455476
337 + 31455139 = 31455476
373 + 31455103 = 31455476
523 + 31454953 = 31455476

Showing the first eight; more decompositions exist.
