Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498878, here are decompositions:

19 + 498859 = 498878
97 + 498781 = 498878
139 + 498739 = 498878
199 + 498679 = 498878
409 + 498469 = 498878
439 + 498439 = 498878
487 + 498391 = 498878
547 + 498331 = 498878

Showing the first eight; more decompositions exist.
