Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513336, here are decompositions:

3 + 31513333 = 31513336
5 + 31513331 = 31513336
149 + 31513187 = 31513336
263 + 31513073 = 31513336
389 + 31512947 = 31513336
443 + 31512893 = 31513336
467 + 31512869 = 31513336
509 + 31512827 = 31513336

Showing the first eight; more decompositions exist.
