Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553178, here are decompositions:

7 + 553171 = 553178
37 + 553141 = 553178
79 + 553099 = 553178
127 + 553051 = 553178
331 + 552847 = 553178
337 + 552841 = 553178
421 + 552757 = 553178
709 + 552469 = 553178

Showing the first eight; more decompositions exist.
