Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481972, here are decompositions:

89 + 481883 = 481972
251 + 481721 = 481972
353 + 481619 = 481972
383 + 481589 = 481972
401 + 481571 = 481972
503 + 481469 = 481972
563 + 481409 = 481972
593 + 481379 = 481972

Showing the first eight; more decompositions exist.
