Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527598, here are decompositions:

29 + 31527569 = 31527598
101 + 31527497 = 31527598
107 + 31527491 = 31527598
191 + 31527407 = 31527598
281 + 31527317 = 31527598
449 + 31527149 = 31527598
467 + 31527131 = 31527598
491 + 31527107 = 31527598

Showing the first eight; more decompositions exist.
