Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611348, here are decompositions:

7 + 31611341 = 31611348
19 + 31611329 = 31611348
29 + 31611319 = 31611348
37 + 31611311 = 31611348
47 + 31611301 = 31611348
211 + 31611137 = 31611348
281 + 31611067 = 31611348
311 + 31611037 = 31611348

Showing the first eight; more decompositions exist.
