Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535886, here are decompositions:

7 + 31535879 = 31535886
59 + 31535827 = 31535886
89 + 31535797 = 31535886
139 + 31535747 = 31535886
229 + 31535657 = 31535886
293 + 31535593 = 31535886
337 + 31535549 = 31535886
383 + 31535503 = 31535886

Showing the first eight; more decompositions exist.
