Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465636, here are decompositions:

5 + 31465631 = 31465636
17 + 31465619 = 31465636
89 + 31465547 = 31465636
107 + 31465529 = 31465636
347 + 31465289 = 31465636
443 + 31465193 = 31465636
809 + 31464827 = 31465636
827 + 31464809 = 31465636

Showing the first eight; more decompositions exist.
