Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505606, here are decompositions:

7 + 31505599 = 31505606
37 + 31505569 = 31505606
73 + 31505533 = 31505606
79 + 31505527 = 31505606
163 + 31505443 = 31505606
277 + 31505329 = 31505606
313 + 31505293 = 31505606
463 + 31505143 = 31505606

Showing the first eight; more decompositions exist.
