Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555242, here are decompositions:

151 + 555091 = 555242
199 + 555043 = 555242
283 + 554959 = 555242
349 + 554893 = 555242
409 + 554833 = 555242
421 + 554821 = 555242
439 + 554803 = 555242
463 + 554779 = 555242

Showing the first eight; more decompositions exist.
