Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548720, here are decompositions:

13 + 548707 = 548720
43 + 548677 = 548720
97 + 548623 = 548720
163 + 548557 = 548720
199 + 548521 = 548720
313 + 548407 = 548720
349 + 548371 = 548720
373 + 548347 = 548720

Showing the first eight; more decompositions exist.
