Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527106, here are decompositions:

29 + 31527077 = 31527106
59 + 31527047 = 31527106
89 + 31527017 = 31527106
167 + 31526939 = 31527106
179 + 31526927 = 31527106
227 + 31526879 = 31527106
353 + 31526753 = 31527106
383 + 31526723 = 31527106

Showing the first eight; more decompositions exist.
