Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547054, here are decompositions:

67 + 31546987 = 31547054
73 + 31546981 = 31547054
163 + 31546891 = 31547054
193 + 31546861 = 31547054
211 + 31546843 = 31547054
223 + 31546831 = 31547054
241 + 31546813 = 31547054
313 + 31546741 = 31547054

Showing the first eight; more decompositions exist.
