Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527694, here are decompositions:

5 + 31527689 = 31527694
17 + 31527677 = 31527694
173 + 31527521 = 31527694
197 + 31527497 = 31527694
281 + 31527413 = 31527694
383 + 31527311 = 31527694
461 + 31527233 = 31527694
503 + 31527191 = 31527694

Showing the first eight; more decompositions exist.
