Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543544, here are decompositions:

13 + 31543531 = 31543544
271 + 31543273 = 31543544
313 + 31543231 = 31543544
337 + 31543207 = 31543544
577 + 31542967 = 31543544
601 + 31542943 = 31543544
607 + 31542937 = 31543544
733 + 31542811 = 31543544

Showing the first eight; more decompositions exist.
