Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529106, here are decompositions:

17 + 31529089 = 31529106
19 + 31529087 = 31529106
53 + 31529053 = 31529106
109 + 31528997 = 31529106
113 + 31528993 = 31529106
137 + 31528969 = 31529106
139 + 31528967 = 31529106
197 + 31528909 = 31529106

Showing the first eight; more decompositions exist.
