Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527232, here are decompositions:

41 + 31527191 = 31527232
59 + 31527173 = 31527232
83 + 31527149 = 31527232
89 + 31527143 = 31527232
101 + 31527131 = 31527232
293 + 31526939 = 31527232
311 + 31526921 = 31527232
353 + 31526879 = 31527232

Showing the first eight; more decompositions exist.
