Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578698, here are decompositions:

5 + 578693 = 578698
11 + 578687 = 578698
89 + 578609 = 578698
101 + 578597 = 578698
257 + 578441 = 578698
389 + 578309 = 578698
401 + 578297 = 578698
431 + 578267 = 578698

Showing the first eight; more decompositions exist.
