Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611408, here are decompositions:

5 + 31611403 = 31611408
29 + 31611379 = 31611408
41 + 31611367 = 31611408
67 + 31611341 = 31611408
79 + 31611329 = 31611408
89 + 31611319 = 31611408
97 + 31611311 = 31611408
107 + 31611301 = 31611408

Showing the first eight; more decompositions exist.
