Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548318, here are decompositions:

79 + 548239 = 548318
97 + 548221 = 548318
229 + 548089 = 548318
367 + 547951 = 548318
409 + 547909 = 548318
487 + 547831 = 548318
499 + 547819 = 548318
571 + 547747 = 548318

Showing the first eight; more decompositions exist.
