Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527732, here are decompositions:

23 + 31527709 = 31527732
29 + 31527703 = 31527732
31 + 31527701 = 31527732
43 + 31527689 = 31527732
73 + 31527659 = 31527732
149 + 31527583 = 31527732
163 + 31527569 = 31527732
191 + 31527541 = 31527732

Showing the first eight; more decompositions exist.
