Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532702, here are decompositions:

43 + 31532659 = 31532702
109 + 31532593 = 31532702
151 + 31532551 = 31532702
163 + 31532539 = 31532702
181 + 31532521 = 31532702
349 + 31532353 = 31532702
373 + 31532329 = 31532702
379 + 31532323 = 31532702

Showing the first eight; more decompositions exist.
