Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527436, here are decompositions:

23 + 31527413 = 31527436
29 + 31527407 = 31527436
47 + 31527389 = 31527436
113 + 31527323 = 31527436
263 + 31527173 = 31527436
293 + 31527143 = 31527436
359 + 31527077 = 31527436
389 + 31527047 = 31527436

Showing the first eight; more decompositions exist.
