Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548630, here are decompositions:

7 + 548623 = 548630
73 + 548557 = 548630
97 + 548533 = 548630
109 + 548521 = 548630
127 + 548503 = 548630
223 + 548407 = 548630
283 + 548347 = 548630
307 + 548323 = 548630

Showing the first eight; more decompositions exist.
