Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548242, here are decompositions:

3 + 548239 = 548242
29 + 548213 = 548242
41 + 548201 = 548242
53 + 548189 = 548242
89 + 548153 = 548242
173 + 548069 = 548242
239 + 548003 = 548242
353 + 547889 = 548242

Showing the first eight; more decompositions exist.
