Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532426, here are decompositions:

73 + 31532353 = 31532426
97 + 31532329 = 31532426
103 + 31532323 = 31532426
157 + 31532269 = 31532426
199 + 31532227 = 31532426
223 + 31532203 = 31532426
313 + 31532113 = 31532426
337 + 31532089 = 31532426

Showing the first eight; more decompositions exist.
