Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535828, here are decompositions:

7 + 31535821 = 31535828
19 + 31535809 = 31535828
31 + 31535797 = 31535828
157 + 31535671 = 31535828
277 + 31535551 = 31535828
409 + 31535419 = 31535828
487 + 31535341 = 31535828
601 + 31535227 = 31535828

Showing the first eight; more decompositions exist.
