Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505634, here are decompositions:

11 + 31505623 = 31505634
67 + 31505567 = 31505634
101 + 31505533 = 31505634
107 + 31505527 = 31505634
113 + 31505521 = 31505634
191 + 31505443 = 31505634
263 + 31505371 = 31505634
313 + 31505321 = 31505634

Showing the first eight; more decompositions exist.
