Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527504, here are decompositions:

5 + 31527499 = 31527504
7 + 31527497 = 31527504
13 + 31527491 = 31527504
23 + 31527481 = 31527504
97 + 31527407 = 31527504
181 + 31527323 = 31527504
193 + 31527311 = 31527504
227 + 31527277 = 31527504

Showing the first eight; more decompositions exist.
