Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557476, here are decompositions:

43 + 31557433 = 31557476
109 + 31557367 = 31557476
193 + 31557283 = 31557476
199 + 31557277 = 31557476
229 + 31557247 = 31557476
277 + 31557199 = 31557476
283 + 31557193 = 31557476
337 + 31557139 = 31557476

Showing the first eight; more decompositions exist.
