Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547726, here are decompositions:

19 + 31547707 = 31547726
43 + 31547683 = 31547726
97 + 31547629 = 31547726
109 + 31547617 = 31547726
277 + 31547449 = 31547726
313 + 31547413 = 31547726
409 + 31547317 = 31547726
439 + 31547287 = 31547726

Showing the first eight; more decompositions exist.
