Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548158, here are decompositions:

5 + 548153 = 548158
41 + 548117 = 548158
59 + 548099 = 548158
89 + 548069 = 548158
257 + 547901 = 548158
269 + 547889 = 548158
389 + 547769 = 548158
431 + 547727 = 548158

Showing the first eight; more decompositions exist.
