Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548540, here are decompositions:

7 + 548533 = 548540
19 + 548521 = 548540
37 + 548503 = 548540
79 + 548461 = 548540
193 + 548347 = 548540
277 + 548263 = 548540
313 + 548227 = 548540
397 + 548143 = 548540

Showing the first eight; more decompositions exist.
