Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546726, here are decompositions:

5 + 31546721 = 31546726
17 + 31546709 = 31546726
89 + 31546637 = 31546726
173 + 31546553 = 31546726
257 + 31546469 = 31546726
269 + 31546457 = 31546726
389 + 31546337 = 31546726
443 + 31546283 = 31546726

Showing the first eight; more decompositions exist.
