Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454754, here are decompositions:

13 + 31454741 = 31454754
17 + 31454737 = 31454754
53 + 31454701 = 31454754
73 + 31454681 = 31454754
101 + 31454653 = 31454754
103 + 31454651 = 31454754
127 + 31454627 = 31454754
167 + 31454587 = 31454754

Showing the first eight; more decompositions exist.
