Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547304, here are decompositions:

7 + 31547297 = 31547304
17 + 31547287 = 31547304
23 + 31547281 = 31547304
37 + 31547267 = 31547304
43 + 31547261 = 31547304
73 + 31547231 = 31547304
101 + 31547203 = 31547304
127 + 31547177 = 31547304

Showing the first eight; more decompositions exist.
