Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455026, here are decompositions:

73 + 31454953 = 31455026
103 + 31454923 = 31455026
199 + 31454827 = 31455026
373 + 31454653 = 31455026
439 + 31454587 = 31455026
643 + 31454383 = 31455026
829 + 31454197 = 31455026
877 + 31454149 = 31455026

Showing the first eight; more decompositions exist.
