Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452382, here are decompositions:

41 + 31452341 = 31452382
149 + 31452233 = 31452382
173 + 31452209 = 31452382
179 + 31452203 = 31452382
251 + 31452131 = 31452382
293 + 31452089 = 31452382
383 + 31451999 = 31452382
389 + 31451993 = 31452382

Showing the first eight; more decompositions exist.
