Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547504, here are decompositions:

223 + 31547281 = 31547504
523 + 31546981 = 31547504
613 + 31546891 = 31547504
643 + 31546861 = 31547504
661 + 31546843 = 31547504
673 + 31546831 = 31547504
691 + 31546813 = 31547504
787 + 31546717 = 31547504

Showing the first eight; more decompositions exist.
