Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548830, here are decompositions:

3 + 548827 = 548830
47 + 548783 = 548830
59 + 548771 = 548830
137 + 548693 = 548830
173 + 548657 = 548830
239 + 548591 = 548830
251 + 548579 = 548830
263 + 548567 = 548830

Showing the first eight; more decompositions exist.
