Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535826, here are decompositions:

5 + 31535821 = 31535826
17 + 31535809 = 31535826
29 + 31535797 = 31535826
73 + 31535753 = 31535826
79 + 31535747 = 31535826
109 + 31535717 = 31535826
193 + 31535633 = 31535826
233 + 31535593 = 31535826

Showing the first eight; more decompositions exist.
