Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529184, here are decompositions:

17 + 31529167 = 31529184
97 + 31529087 = 31529184
103 + 31529081 = 31529184
131 + 31529053 = 31529184
191 + 31528993 = 31529184
331 + 31528853 = 31529184
353 + 31528831 = 31529184
373 + 31528811 = 31529184

Showing the first eight; more decompositions exist.
