Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527506, here are decompositions:

7 + 31527499 = 31527506
163 + 31527343 = 31527506
229 + 31527277 = 31527506
313 + 31527193 = 31527506
349 + 31527157 = 31527506
397 + 31527109 = 31527506
607 + 31526899 = 31527506
613 + 31526893 = 31527506

Showing the first eight; more decompositions exist.
