Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454954, here are decompositions:

31 + 31454923 = 31454954
73 + 31454881 = 31454954
127 + 31454827 = 31454954
367 + 31454587 = 31454954
457 + 31454497 = 31454954
523 + 31454431 = 31454954
571 + 31454383 = 31454954
577 + 31454377 = 31454954

Showing the first eight; more decompositions exist.
