Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535086, here are decompositions:

3 + 31535083 = 31535086
5 + 31535081 = 31535086
29 + 31535057 = 31535086
53 + 31535033 = 31535086
173 + 31534913 = 31535086
347 + 31534739 = 31535086
449 + 31534637 = 31535086
593 + 31534493 = 31535086

Showing the first eight; more decompositions exist.
