Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535676, here are decompositions:

5 + 31535671 = 31535676
19 + 31535657 = 31535676
37 + 31535639 = 31535676
43 + 31535633 = 31535676
83 + 31535593 = 31535676
127 + 31535549 = 31535676
173 + 31535503 = 31535676
257 + 31535419 = 31535676

Showing the first eight; more decompositions exist.
