Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454906, here are decompositions:

3 + 31454903 = 31454906
79 + 31454827 = 31454906
97 + 31454809 = 31454906
409 + 31454497 = 31454906
523 + 31454383 = 31454906
643 + 31454263 = 31454906
709 + 31454197 = 31454906
757 + 31454149 = 31454906

Showing the first eight; more decompositions exist.
