Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505834, here are decompositions:

13 + 31505821 = 31505834
67 + 31505767 = 31505834
97 + 31505737 = 31505834
103 + 31505731 = 31505834
211 + 31505623 = 31505834
307 + 31505527 = 31505834
313 + 31505521 = 31505834
463 + 31505371 = 31505834

Showing the first eight; more decompositions exist.
