Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611404, here are decompositions:

37 + 31611367 = 31611404
103 + 31611301 = 31611404
241 + 31611163 = 31611404
277 + 31611127 = 31611404
337 + 31611067 = 31611404
367 + 31611037 = 31611404
613 + 31610791 = 31611404
631 + 31610773 = 31611404

Showing the first eight; more decompositions exist.
