Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535766, here are decompositions:

13 + 31535753 = 31535766
19 + 31535747 = 31535766
109 + 31535657 = 31535766
127 + 31535639 = 31535766
173 + 31535593 = 31535766
263 + 31535503 = 31535766
337 + 31535429 = 31535766
347 + 31535419 = 31535766

Showing the first eight; more decompositions exist.
