Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611494, here are decompositions:

7 + 31611487 = 31611494
37 + 31611457 = 31611494
127 + 31611367 = 31611494
193 + 31611301 = 31611494
223 + 31611271 = 31611494
307 + 31611187 = 31611494
331 + 31611163 = 31611494
367 + 31611127 = 31611494

Showing the first eight; more decompositions exist.
