Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527532, here are decompositions:

11 + 31527521 = 31527532
41 + 31527491 = 31527532
359 + 31527173 = 31527532
383 + 31527149 = 31527532
389 + 31527143 = 31527532
401 + 31527131 = 31527532
521 + 31527011 = 31527532
593 + 31526939 = 31527532

Showing the first eight; more decompositions exist.
