Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535196, here are decompositions:

13 + 31535183 = 31535196
23 + 31535173 = 31535196
53 + 31535143 = 31535196
73 + 31535123 = 31535196
83 + 31535113 = 31535196
89 + 31535107 = 31535196
113 + 31535083 = 31535196
137 + 31535059 = 31535196

Showing the first eight; more decompositions exist.
