Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527706, here are decompositions:

3 + 31527703 = 31527706
5 + 31527701 = 31527706
17 + 31527689 = 31527706
29 + 31527677 = 31527706
47 + 31527659 = 31527706
137 + 31527569 = 31527706
173 + 31527533 = 31527706
293 + 31527413 = 31527706

Showing the first eight; more decompositions exist.
