Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454996, here are decompositions:

43 + 31454953 = 31454996
73 + 31454923 = 31454996
409 + 31454587 = 31454996
499 + 31454497 = 31454996
607 + 31454389 = 31454996
613 + 31454383 = 31454996
619 + 31454377 = 31454996
733 + 31454263 = 31454996

Showing the first eight; more decompositions exist.
