Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535776, here are decompositions:

23 + 31535753 = 31535776
29 + 31535747 = 31535776
59 + 31535717 = 31535776
137 + 31535639 = 31535776
227 + 31535549 = 31535776
347 + 31535429 = 31535776
353 + 31535423 = 31535776
359 + 31535417 = 31535776

Showing the first eight; more decompositions exist.
