Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455326, here are decompositions:

13 + 31455313 = 31455326
103 + 31455223 = 31455326
223 + 31455103 = 31455326
373 + 31454953 = 31455326
499 + 31454827 = 31455326
673 + 31454653 = 31455326
739 + 31454587 = 31455326
829 + 31454497 = 31455326

Showing the first eight; more decompositions exist.
