Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557464, here are decompositions:

31 + 31557433 = 31557464
73 + 31557391 = 31557464
97 + 31557367 = 31557464
181 + 31557283 = 31557464
223 + 31557241 = 31557464
271 + 31557193 = 31557464
277 + 31557187 = 31557464
457 + 31557007 = 31557464

Showing the first eight; more decompositions exist.
