Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535926, here are decompositions:

17 + 31535909 = 31535926
47 + 31535879 = 31535926
173 + 31535753 = 31535926
179 + 31535747 = 31535926
269 + 31535657 = 31535926
293 + 31535633 = 31535926
503 + 31535423 = 31535926
509 + 31535417 = 31535926

Showing the first eight; more decompositions exist.
