Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547002, here are decompositions:

5 + 31546997 = 31547002
89 + 31546913 = 31547002
281 + 31546721 = 31547002
293 + 31546709 = 31547002
401 + 31546601 = 31547002
419 + 31546583 = 31547002
449 + 31546553 = 31547002
653 + 31546349 = 31547002

Showing the first eight; more decompositions exist.
