Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461978, here are decompositions:

7 + 461971 = 461978
61 + 461917 = 461978
271 + 461707 = 461978
379 + 461599 = 461978
397 + 461581 = 461978
409 + 461569 = 461978
457 + 461521 = 461978
499 + 461479 = 461978

Showing the first eight; more decompositions exist.
