Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527432, here are decompositions:

19 + 31527413 = 31527432
43 + 31527389 = 31527432
89 + 31527343 = 31527432
109 + 31527323 = 31527432
179 + 31527253 = 31527432
199 + 31527233 = 31527432
239 + 31527193 = 31527432
241 + 31527191 = 31527432

Showing the first eight; more decompositions exist.
