Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541424, here are decompositions:

7 + 31541417 = 31541424
23 + 31541401 = 31541424
127 + 31541297 = 31541424
157 + 31541267 = 31541424
181 + 31541243 = 31541424
191 + 31541233 = 31541424
251 + 31541173 = 31541424
263 + 31541161 = 31541424

Showing the first eight; more decompositions exist.
