Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505534, here are decompositions:

7 + 31505527 = 31505534
13 + 31505521 = 31505534
61 + 31505473 = 31505534
103 + 31505431 = 31505534
163 + 31505371 = 31505534
241 + 31505293 = 31505534
397 + 31505137 = 31505534
457 + 31505077 = 31505534

Showing the first eight; more decompositions exist.
