Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513322, here are decompositions:

13 + 31513309 = 31513322
19 + 31513303 = 31513322
103 + 31513219 = 31513322
109 + 31513213 = 31513322
199 + 31513123 = 31513322
331 + 31512991 = 31513322
409 + 31512913 = 31513322
499 + 31512823 = 31513322

Showing the first eight; more decompositions exist.
