Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608692, here are decompositions:

103 + 31608589 = 31608692
163 + 31608529 = 31608692
211 + 31608481 = 31608692
373 + 31608319 = 31608692
421 + 31608271 = 31608692
523 + 31608169 = 31608692
601 + 31608091 = 31608692
631 + 31608061 = 31608692

Showing the first eight; more decompositions exist.
