Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527488, here are decompositions:

7 + 31527481 = 31527488
211 + 31527277 = 31527488
241 + 31527247 = 31527488
277 + 31527211 = 31527488
331 + 31527157 = 31527488
337 + 31527151 = 31527488
379 + 31527109 = 31527488
547 + 31526941 = 31527488

Showing the first eight; more decompositions exist.
