Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519336, here are decompositions:

29 + 31519307 = 31519336
47 + 31519289 = 31519336
83 + 31519253 = 31519336
89 + 31519247 = 31519336
137 + 31519199 = 31519336
227 + 31519109 = 31519336
263 + 31519073 = 31519336
269 + 31519067 = 31519336

Showing the first eight; more decompositions exist.
