Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509614, here are decompositions:

13 + 31509601 = 31509614
43 + 31509571 = 31509614
61 + 31509553 = 31509614
127 + 31509487 = 31509614
181 + 31509433 = 31509614
211 + 31509403 = 31509614
271 + 31509343 = 31509614
277 + 31509337 = 31509614

Showing the first eight; more decompositions exist.
