Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527592, here are decompositions:

23 + 31527569 = 31527592
59 + 31527533 = 31527592
71 + 31527521 = 31527592
101 + 31527491 = 31527592
179 + 31527413 = 31527592
269 + 31527323 = 31527592
281 + 31527311 = 31527592
359 + 31527233 = 31527592

Showing the first eight; more decompositions exist.
