Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548722, here are decompositions:

3 + 548719 = 548722
29 + 548693 = 548722
131 + 548591 = 548722
179 + 548543 = 548722
233 + 548489 = 548722
263 + 548459 = 548722
269 + 548453 = 548722
281 + 548441 = 548722

Showing the first eight; more decompositions exist.
