Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608392, here are decompositions:

43 + 31608349 = 31608392
73 + 31608319 = 31608392
223 + 31608169 = 31608392
229 + 31608163 = 31608392
331 + 31608061 = 31608392
379 + 31608013 = 31608392
421 + 31607971 = 31608392
523 + 31607869 = 31608392

Showing the first eight; more decompositions exist.
