Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509346, here are decompositions:

3 + 31509343 = 31509346
17 + 31509329 = 31509346
23 + 31509323 = 31509346
173 + 31509173 = 31509346
269 + 31509077 = 31509346
293 + 31509053 = 31509346
317 + 31509029 = 31509346
347 + 31508999 = 31509346

Showing the first eight; more decompositions exist.
