Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531662, here are decompositions:

13 + 31531649 = 31531662
23 + 31531639 = 31531662
83 + 31531579 = 31531662
139 + 31531523 = 31531662
179 + 31531483 = 31531662
191 + 31531471 = 31531662
241 + 31531421 = 31531662
263 + 31531399 = 31531662

Showing the first eight; more decompositions exist.
