Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543218, here are decompositions:

31 + 543187 = 543218
61 + 543157 = 543218
79 + 543139 = 543218
157 + 543061 = 543218
199 + 543019 = 543218
271 + 542947 = 543218
307 + 542911 = 543218
397 + 542821 = 543218

Showing the first eight; more decompositions exist.
