Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547534, here are decompositions:

3 + 31547531 = 31547534
331 + 31547203 = 31547534
373 + 31547161 = 31547534
433 + 31547101 = 31547534
457 + 31547077 = 31547534
547 + 31546987 = 31547534
643 + 31546891 = 31547534
673 + 31546861 = 31547534

Showing the first eight; more decompositions exist.
