Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547236, here are decompositions:

5 + 31547231 = 31547236
59 + 31547177 = 31547236
89 + 31547147 = 31547236
107 + 31547129 = 31547236
173 + 31547063 = 31547236
197 + 31547039 = 31547236
233 + 31547003 = 31547236
239 + 31546997 = 31547236

Showing the first eight; more decompositions exist.
