Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547300, here are decompositions:

3 + 31547297 = 31547300
13 + 31547287 = 31547300
19 + 31547281 = 31547300
97 + 31547203 = 31547300
139 + 31547161 = 31547300
157 + 31547143 = 31547300
199 + 31547101 = 31547300
223 + 31547077 = 31547300

Showing the first eight; more decompositions exist.
