Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607554, here are decompositions:

3 + 31607551 = 31607554
23 + 31607531 = 31607554
107 + 31607447 = 31607554
131 + 31607423 = 31607554
191 + 31607363 = 31607554
197 + 31607357 = 31607554
227 + 31607327 = 31607554
257 + 31607297 = 31607554

Showing the first eight; more decompositions exist.
