Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547248, here are decompositions:

17 + 31547231 = 31547248
71 + 31547177 = 31547248
101 + 31547147 = 31547248
251 + 31546997 = 31547248
311 + 31546937 = 31547248
401 + 31546847 = 31547248
431 + 31546817 = 31547248
449 + 31546799 = 31547248

Showing the first eight; more decompositions exist.
