Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527636, here are decompositions:

53 + 31527583 = 31527636
59 + 31527577 = 31527636
67 + 31527569 = 31527636
103 + 31527533 = 31527636
113 + 31527523 = 31527636
137 + 31527499 = 31527636
139 + 31527497 = 31527636
223 + 31527413 = 31527636

Showing the first eight; more decompositions exist.
