Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572222, here are decompositions:

43 + 572179 = 572222
61 + 572161 = 572222
163 + 572059 = 572222
181 + 572041 = 572222
199 + 572023 = 572222
283 + 571939 = 572222
349 + 571873 = 572222
421 + 571801 = 572222

Showing the first eight; more decompositions exist.
