Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547264, here are decompositions:

3 + 31547261 = 31547264
61 + 31547203 = 31547264
103 + 31547161 = 31547264
163 + 31547101 = 31547264
277 + 31546987 = 31547264
283 + 31546981 = 31547264
373 + 31546891 = 31547264
421 + 31546843 = 31547264

Showing the first eight; more decompositions exist.
