Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452426, here are decompositions:

7 + 31452419 = 31452426
59 + 31452367 = 31452426
193 + 31452233 = 31452426
223 + 31452203 = 31452426
227 + 31452199 = 31452426
337 + 31452089 = 31452426
347 + 31452079 = 31452426
419 + 31452007 = 31452426

Showing the first eight; more decompositions exist.
