Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611456, here are decompositions:

17 + 31611439 = 31611456
53 + 31611403 = 31611456
89 + 31611367 = 31611456
127 + 31611329 = 31611456
137 + 31611319 = 31611456
157 + 31611299 = 31611456
269 + 31611187 = 31611456
293 + 31611163 = 31611456

Showing the first eight; more decompositions exist.
