Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547412, here are decompositions:

73 + 31547339 = 31547412
109 + 31547303 = 31547412
131 + 31547281 = 31547412
151 + 31547261 = 31547412
181 + 31547231 = 31547412
251 + 31547161 = 31547412
269 + 31547143 = 31547412
283 + 31547129 = 31547412

Showing the first eight; more decompositions exist.
