Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536016, here are decompositions:

107 + 31535909 = 31536016
137 + 31535879 = 31536016
263 + 31535753 = 31536016
269 + 31535747 = 31536016
359 + 31535657 = 31536016
383 + 31535633 = 31536016
467 + 31535549 = 31536016
587 + 31535429 = 31536016

Showing the first eight; more decompositions exist.
