Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535860, here are decompositions:

29 + 31535831 = 31535860
107 + 31535753 = 31535860
113 + 31535747 = 31535860
179 + 31535681 = 31535860
227 + 31535633 = 31535860
269 + 31535591 = 31535860
311 + 31535549 = 31535860
431 + 31535429 = 31535860

Showing the first eight; more decompositions exist.
