Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535678, here are decompositions:

7 + 31535671 = 31535678
127 + 31535551 = 31535678
211 + 31535467 = 31535678
337 + 31535341 = 31535678
367 + 31535311 = 31535678
547 + 31535131 = 31535678
571 + 31535107 = 31535678
619 + 31535059 = 31535678

Showing the first eight; more decompositions exist.
