Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547330, here are decompositions:

13 + 31547317 = 31547330
43 + 31547287 = 31547330
127 + 31547203 = 31547330
229 + 31547101 = 31547330
349 + 31546981 = 31547330
421 + 31546909 = 31547330
439 + 31546891 = 31547330
487 + 31546843 = 31547330

Showing the first eight; more decompositions exist.
