Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513434, here are decompositions:

11 + 31513423 = 31513434
23 + 31513411 = 31513434
31 + 31513403 = 31513434
61 + 31513373 = 31513434
101 + 31513333 = 31513434
103 + 31513331 = 31513434
131 + 31513303 = 31513434
233 + 31513201 = 31513434

Showing the first eight; more decompositions exist.
