Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513334, here are decompositions:

3 + 31513331 = 31513334
31 + 31513303 = 31513334
211 + 31513123 = 31513334
271 + 31513063 = 31513334
277 + 31513057 = 31513334
331 + 31513003 = 31513334
337 + 31512997 = 31513334
421 + 31512913 = 31513334

Showing the first eight; more decompositions exist.
