Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527606, here are decompositions:

23 + 31527583 = 31527606
29 + 31527577 = 31527606
37 + 31527569 = 31527606
73 + 31527533 = 31527606
83 + 31527523 = 31527606
107 + 31527499 = 31527606
109 + 31527497 = 31527606
193 + 31527413 = 31527606

Showing the first eight; more decompositions exist.
