Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532370, here are decompositions:

17 + 31532353 = 31532370
29 + 31532341 = 31532370
31 + 31532339 = 31532370
41 + 31532329 = 31532370
47 + 31532323 = 31532370
101 + 31532269 = 31532370
109 + 31532261 = 31532370
151 + 31532219 = 31532370

Showing the first eight; more decompositions exist.
