Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535610, here are decompositions:

17 + 31535593 = 31535610
19 + 31535591 = 31535610
59 + 31535551 = 31535610
61 + 31535549 = 31535610
107 + 31535503 = 31535610
181 + 31535429 = 31535610
191 + 31535419 = 31535610
193 + 31535417 = 31535610

Showing the first eight; more decompositions exist.
