Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454526, here are decompositions:

13 + 31454513 = 31454526
29 + 31454497 = 31454526
43 + 31454483 = 31454526
137 + 31454389 = 31454526
149 + 31454377 = 31454526
263 + 31454263 = 31454526
277 + 31454249 = 31454526
307 + 31454219 = 31454526

Showing the first eight; more decompositions exist.
