Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527726, here are decompositions:

17 + 31527709 = 31527726
23 + 31527703 = 31527726
29 + 31527697 = 31527726
37 + 31527689 = 31527726
67 + 31527659 = 31527726
149 + 31527577 = 31527726
157 + 31527569 = 31527726
193 + 31527533 = 31527726

Showing the first eight; more decompositions exist.
